9th Commandment -- Do Not Bear False Witness (Exo 20:16)¶

Question¶

What does the Bible say about the ninth commandment? What does "false witness" (ed sheqer / ed shav) mean -- Exodus uses sheqer (H8267, "lying/deceitful") while Deuteronomy uses shav (H7723, "vain/worthless"). Is this limited to courtroom testimony or does it cover all falsehood? Trace through Leviticus, Proverbs, the prophets, Jesus, Paul, and Revelation.

Summary Answer¶

The ninth commandment (Exo 20:16) prohibits bearing false witness (ed sheqer) against one's neighbor. The Deuteronomic version (Deu 5:20) uses shav (H7723, "emptiness/worthlessness") instead of sheqer (H8267, "falsehood/lying"), creating complementary coverage: testimony that is deliberately false (sheqer) and testimony that is empty, worthless, or groundless (shav). While the commandment's language is legal (the verb anah means "testify" and ed means "witness"), the broader biblical witness expands it far beyond the courtroom to encompass all forms of falsehood -- lying to one another (Lev 19:11; Col 3:9), gossip and slander (Lev 19:16), false reports (Exo 23:1), deceptive dealings (Pro 21:6), idle words (Mat 12:36), and even the inconsistency between profession and practice (1 Jn 2:4). Truthfulness is grounded in the character of God, who cannot lie (Tit 1:2; Heb 6:18; Num 23:19), while lying is rooted in the nature of Satan, who is the father of lies (Jhn 8:44). Christ Himself is "the truth" (Jhn 14:6) and no guile was found in His mouth (1 Pe 2:22). The eschatological consequences are categorical: "all liars" are excluded from the New Jerusalem (Rev 21:8,27; 22:15), while the redeemed are characterized by having "no guile in their mouths" (Rev 14:5).

Key Verses¶

Exodus 20:16 Thou shalt not bear false witness against thy neighbour.

Deuteronomy 5:20 Neither shalt thou bear false witness against thy neighbour.

Leviticus 19:11 Ye shall not steal, neither deal falsely, neither lie one to another.

Proverbs 6:16-19 These six things doth the LORD hate: yea, seven are an abomination unto him: A proud look, a lying tongue, and hands that shed innocent blood, An heart that deviseth wicked imaginations, feet that be swift in running to mischief, A false witness that speaketh lies, and he that soweth discord among brethren.

Proverbs 12:22 Lying lips are abomination to the LORD: but they that deal truly are his delight.

John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

Titus 1:2 In hope of eternal life, which God, that cannot lie, promised before the world began.

Revelation 21:8 ...and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.

2. Necessary Implications¶

#	Necessary Implication	Based on	Why it is unavoidable
N078	The two versions of the ninth commandment (sheqer in Exo 20:16 and shav in Deu 5:20) together prohibit both deliberately false testimony and empty/worthless/groundless testimony, since sheqer denotes intentional lying and shav denotes emptiness/worthlessness (already established as N036 for the linguistic connection)	E521, E239, E522, E203	Sheqer means "lie/falsehood" (active deception) and shav means "emptiness/worthlessness" (groundless claims). These are two different Hebrew words with different semantic ranges. The commandment spoken twice with these different words covers both intentional deception and baseless/empty testimony. No reader can deny that two different words have different meanings.
N079	The ninth commandment extends beyond formal courtroom testimony to all forms of falsehood, because Lev 19:11 prohibits lying "one to another" (not in court), Lev 19:16 prohibits talebearing "among thy people," Exo 23:1 prohibits raising a "false report" (not limited to courts), and Col 3:9/Eph 4:25 prohibit general lying	E521, E524, E470, E527, E554, E555	The commandment uses legal vocabulary ("testify," "witness"), but multiple explicit passages extend the same prohibition to everyday lying (E470), gossip (E527), false reports (E524), and interpersonal deceit (E554, E555). The extensions are stated in the text, not inferred.
N080	The false witness penalty (Deu 19:18-19) is symmetric: whatever the false witness intended to inflict on his victim is inflicted on the false witness instead	E530	The text states "ye shall do unto him as he had thought to have done unto his brother." This is a direct statement of symmetry: intended penalty becomes received penalty. No additional reasoning is required.
N081	Truthfulness is grounded in God's nature, because God "cannot lie" (Tit 1:2), it is "impossible" for God to lie (Heb 6:18), and God is "not a man that he should lie" (Num 23:19), while Christ is "the truth" (Jhn 14:6)	E557, E558, E559, E552	Four passages state God's inability to lie and Christ's identity as truth. That truthfulness is rooted in God's nature follows unavoidably from "God cannot lie" + "Christ IS the truth." Every reader must agree that inability to lie and identity as truth constitute a nature-level attribute.
N082	Lying is rooted in Satan's nature, because the devil "abode not in the truth," has "no truth in him," speaks lies "of his own" (from his own nature), and is called "the father" of lying	E551	Jesus's statement identifies the devil as liar by nature ("no truth IN him," speaks lies "of his own," IS a liar, IS the father of it). These four descriptors in a single verse identify lying as constitutive of Satan's nature. No alternative reading is available.
N083	The NT treats the ninth commandment as continuing in force, because Jesus quotes it as binding (Mat 19:18), Paul lists liars and perjurers alongside other commandment-violators (1 Ti 1:10), Paul commands truth-telling in Decalogue language (Eph 4:25; Col 3:9), and Revelation excludes liars from the eternal kingdom (Rev 21:8; 22:15)	E496, E556, E554, E555, E564, E566	Multiple NT authors (Jesus, Paul, John) treat the prohibition against lying as authoritative. Jesus quotes it directly. Paul commands truth-telling. Revelation pronounces ultimate judgment on liars. No reader can deny that these passages treat the commandment as binding in the NT era.
N084	False witness has lethal potential, because Deu 19:18-19 prescribes life-for-life for false witnesses in capital cases, Pro 25:18 compares a false witness to weapons, the Naboth narrative (1 Ki 21) shows false witness producing murder, and the council sought false witness to execute Jesus (Mat 26:59)	E530, E539, E550	The lex talionis applied to false witness includes "life for life" (Deu 19:21). A false witness is called a weapon (Pro 25:18). False testimony led to Naboth's death and was sought for Jesus's execution. The lethal potential is stated in each passage independently.
N085	The NT commendation of Rahab is for her faith (believing God) and her works (receiving/protecting the spies), not for her lie, because Heb 11:31 specifies "by faith...when she had received the spies" and Jas 2:25 specifies "when she had received the messengers, and had sent them out another way"	E567, E568	Both NT passages specify what Rahab is commended for: receiving/sheltering the spies (faith and works). Neither passage mentions the lie. The text identifies the commended actions; it does not commend the lie.

3. Inferences¶

#	Claim	Type	What the Bible actually says	Why this is an inference	Criteria
I046	The shav/sheqer complementarity in the two versions of the ninth commandment creates a comprehensive prohibition covering the entire spectrum of untruthful testimony -- from deliberate fabrication (sheqer) through careless, empty, or groundless claims (shav) -- forming a unified biblical theology of truthfulness	I-A	E521 (sheqer prohibition), E239 (shav version), E522 (sheqer definition), E203 (shav definition), N078 (complementary coverage), N036 (shav links 3rd and 9th commandments)	Each component is in E/N tables. The claim that these create a "comprehensive prohibition" forming a "unified biblical theology of truthfulness" systematizes the individual lexical data points into a broader doctrinal framework. All vocabulary and concepts come from the text.	#5 (systematizing)
I047	The Bible presents truth and falsehood as a cosmic antithesis rooted in the natures of God and Satan respectively: God cannot lie (Tit 1:2; Heb 6:18), Christ is "the truth" (Jhn 14:6), Christ had no guile (1 Pe 2:22), while the devil is the father of lies (Jhn 8:44), is devoid of truth, and his very name (diabolos) means "slanderer"	I-A	E557 (God cannot lie), E558 (impossible for God to lie), E552 (Christ is truth), E560 (no guile in Christ's mouth), E551 (devil is liar/father of lies), N081 (truthfulness grounded in God), N082 (lying rooted in Satan)	Each individual statement about God's truthfulness and Satan's lying nature is explicit. The claim of a "cosmic antithesis" systematizes these individual statements into a unified theological framework. All components derive from E/N items.	#5 (systematizing)
I048	The ninth commandment functions as a foundation for social order, because its violation produces societal collapse (Isa 59:14 "truth is fallen in the street"), prophetic indictment (Hos 4:1-2, five commandment violations flowing from absence of truth), false witness leading to judicial murder (1 Ki 21; Mat 26:59), and eschatological exclusion (Rev 21:8; 22:15)	I-A	E544 (truth fallen in the street), E546 (absence of truth produces commandment violations), E530 (false witness penalty), E550 (false witnesses against Jesus), E564/E566 (liars excluded from eternity)	Each passage is explicit. The claim that the commandment "functions as a foundation for social order" synthesizes the prophetic, legal, narrative, and eschatological data into a sociological assessment. The synthesis goes beyond what any individual text states.	#5 (systematizing)
I049	The Rahab and midwives narratives present cases where God blessed individuals who acted in faith to preserve life in contexts where deception also occurred, but the biblical text consistently commends their faith and life-preserving actions rather than the deception itself, and the broader biblical testimony uniformly condemns all forms of lying	I-A	E567 (Rahab commended for faith in receiving spies), E568 (Rahab commended for works in receiving/sending messengers), E569 (midwives feared God, God blessed them), N085 (commendation is for faith/works, not the lie), E521 (the commandment), E532 (lying is abomination), E551 (lying from Satan), E564 (liars in lake of fire)	Each element is in E/N: the commendation texts (E567-E569), the analysis of what is commended (N085), and the broader lying prohibition (E521, E532, E551, E564). The systematization of these into a unified assessment of how the Bible "treats" these difficult cases requires synthesizing narrative, didactic, and eschatological texts.	#5 (systematizing)
I050	Paul's vice list in 1 Timothy 1:9-10 follows the Decalogue order (murderers = 6th, whoremongers = 7th, menstealers = 8th, liars/perjurers = 9th), demonstrating that the Decalogue structure governed NT moral reasoning and that each commandment remains operative	I-A	E556 (Paul lists liars/perjurers), E496 (Jesus quotes 9th commandment), E495/Mat 15:19 (Jesus lists false witness), E390/Rom 13:9 (Paul quotes Decalogue commands), N083 (NT treats 9th as continuing)	Each passage is explicit. The claim that this "demonstrates Decalogue structure governed NT moral reasoning" and that "each commandment remains operative" systematizes the ordering observation into a doctrinal conclusion about ongoing authority.	#5 (systematizing)

Verification Phase¶

Step A: Verify Explicit Statements¶

E521-E569: Each statement directly quotes or closely paraphrases actual verse text. Each represents the plain lexical meaning of the words in the cited verse(s).
Items identified as already registered (E239, E203, E470, E211, E222, E495, E496, E244, E183, E389, E136, E402, E454, E137, E455) are noted with their existing IDs and received "also-in" entries rather than new registrations.
New items (E521-E569, 49 items) are verified as genuine explicit statements.

Step B: Verify Necessary Implications¶

N078 (shav/sheqer complementarity): Two different words with documented different meanings used in the same grammatical slot. Unavoidable conclusion that different words convey different nuances. Pass all three N-tier tests.
N079 (scope beyond courtroom): Multiple explicit texts extend the prohibition to non-legal contexts. The texts themselves make the extension. Pass.
N080 (symmetric penalty): Deu 19:18-19 states the symmetry directly. Pass.
N081 (truthfulness in God's nature): Four passages state God's inability to lie and Christ's identity as truth. Pass.
N082 (lying in Satan's nature): Jhn 8:44 contains four descriptors identifying lying as constitutive of Satan. Pass.
N083 (NT continuation): Multiple NT authors treat the commandment as binding. Pass.
N084 (lethal potential): Lex talionis includes life-for-life; weapon comparison; narrative demonstration. Pass.
N085 (Rahab commended for faith, not lie): Both NT passages specify the commended actions. Pass.

Step C: Verify Inference Classifications (Source Test)¶

I046-I050: Each claim's components are found in the E/N tables. Stripped of systematization, all vocabulary and concepts come from E/N items. Text-derived (I-A or I-B).

Step D: Verify Inference Classifications (Direction Test)¶

I046-I050: None require any E/N statement to mean something other than its plain lexical value. They only systematize multiple E/N items into broader frameworks. I-A confirmed for all.

Step E: Consistency Checks¶

Every I-A (I046-I050): Each requires only criterion #5 (systematizing). None require adding concepts (#1), choosing between readings (#2), or applying external frameworks (#3). Pass.
No I-B items present. No I-D items present.

What CAN Be Said (Scripture explicitly states or necessarily implies)¶

God prohibits bearing false witness (ed sheqer) against one's neighbor (Exo 20:16).
The Deuteronomic version uses shav (emptiness/worthlessness) instead of sheqer (falsehood), creating complementary coverage: both deliberate lies and groundless/empty testimony are prohibited (Exo 20:16; Deu 5:20; N078).
The same word shav connects the 3rd commandment ("God's name in vain") and the 9th commandment ("false witness"), linking false testimony against one's neighbor with bearing God's name emptily (N036, E239).
The scope extends beyond courtroom testimony to all forms of interpersonal falsehood: lying to one another (Lev 19:11), gossip/talebearing (Lev 19:16), false reports (Exo 23:1), and general deceitful speech (Col 3:9; Eph 4:25) (N079).
A person who witnesses something and refuses to testify when adjured bears guilt -- silence under oath is sin (Lev 5:1).
Two or three witnesses are required for capital cases (Num 35:30; Deu 17:6-7), and witnesses must cast the first stone, ensuring personal accountability.
A false witness receives the punishment he intended to inflict on his victim -- the lex talionis applied to perjury (Deu 19:18-19; N080).
Lying is one of the seven things the LORD hates and considers an abomination (Pro 6:16-19).
Lying lips are an abomination to the LORD; those who deal truly are His delight (Pro 12:22).
A false witness is compared to lethal weapons: maul, sword, and sharp arrow (Pro 25:18).
Truth endures permanently; lying is temporary (Pro 12:19).
Truthfulness is grounded in God's nature: He cannot lie (Tit 1:2; Heb 6:18; Num 23:19), and Christ is "the truth" (Jhn 14:6) (N081).
Lying is rooted in Satan's nature: he has no truth in him, speaks lies from his own nature, and is the father of lying (Jhn 8:44) (N082).
Christ fulfilled the 9th commandment perfectly: "no guile was found in his mouth" (1 Pe 2:22; Isa 53:9).
Jesus locates false witness in the heart (Mat 15:19), intensifies the truth standard ("let your yea be yea," Mat 5:37), and extends accountability to idle words (Mat 12:36).
Jesus explicitly quotes the 9th commandment as authoritative (Mat 19:18; Mrk 10:19).
The NT treats the 9th commandment as continuing in force: Paul commands truth-telling (Eph 4:25; Col 3:9), lists liars/perjurers alongside other commandment-violators (1 Ti 1:10), and Revelation excludes liars from eternity (Rev 21:8; 22:15) (N083).
Lying to the Holy Spirit resulted in immediate death for Ananias and Sapphira (Act 5:3-4).
The eschatological saints are characterized by no guile in their mouths (Rev 14:5; Zep 3:13).
All liars are consigned to the lake of fire (Rev 21:8); nothing that makes a lie enters the New Jerusalem (Rev 21:27); those who love and make lies are excluded (Rev 22:15).
The NT commendations of Rahab are for her faith (receiving spies) and works (sheltering/sending them), not for her lie (Heb 11:31; Jas 2:25) (N085). The midwives are blessed because they feared God (Exo 1:21).

What CANNOT Be Said (not explicitly stated or necessarily implied by Scripture)¶

The text does not state that the ninth commandment is limited to courtroom testimony -- the broader biblical witness explicitly extends it to all forms of falsehood.
The text does not state that Rahab or the midwives were commended FOR their deception. The commendation is tied to their faith and God-fearing actions, not to the specific statements made.
The text does not state that "white lies" or "well-intentioned" deception are acceptable. No category of permissible lying is established in the biblical text.
The text does not state a complete hierarchy of duties (e.g., whether saving life overrides truth-telling in all cases). The Rahab and midwives narratives describe what happened and note God's blessing on their faith/fear of God, but no general principle of permissible deception is articulated.
The text does not state that every individual instance of hyperbole, rhetorical question, parable, or literary device constitutes "lying" -- the commandment addresses misrepresentation of fact in testimony and interpersonal dealings.
The text does not state the precise mechanism by which the two versions (sheqer and shav) came to differ -- whether Moses chose a complementary term or God spoke both.
The text does not state that the "lying spirit" episode (1 Ki 22:21-23) makes God a liar. God permitted the deception of Ahab through false prophets while simultaneously revealing the truth through Micaiah.

Final Synthesis¶

The ninth commandment -- "Thou shalt not bear false witness against thy neighbour" (Exo 20:16) -- prohibits testifying falsely (ed sheqer) against one's fellow. The Deuteronomic version (Deu 5:20) substitutes shav (emptiness, worthlessness) for sheqer (falsehood), creating complementary coverage: both deliberate deception and empty, groundless testimony are condemned. The same word shav connects this commandment to the third commandment (Exo 20:7), binding the prohibition against false witness toward one's neighbor with the prohibition against bearing God's name in vain.

The commandment's Hebrew structure. The verb anah (H6030, "to answer/testify") carries a legal testimonial sense. The construct chain ed sheqer / ed shav means "a witness of falsehood" or "a witness of emptiness." The preposition be with rea ("against your neighbor") establishes the interpersonal dimension. The literal sense is: "You shall not testify against your neighbor as a lying/worthless witness."

Scope: from courtroom to all of life. The commandment's language is legal, but the broader biblical witness extends it progressively. Leviticus 19:11 prohibits lying "one to another" -- not a courtroom setting. Leviticus 19:16 prohibits talebearing "among thy people." Exodus 23:1 prohibits raising a "false report" (shema shav). Proverbs addresses lying in commercial dealings (Pro 21:6), neighborly relations (Pro 26:18-19), and habitual speech (Pro 12:22). Jesus extends accountability to "every idle word" (Mat 12:36). Paul commands believers to put away lying and speak truth (Eph 4:25; Col 3:9). John identifies inconsistency between profession and practice as lying (1 Jn 2:4). The scope of the prohibition expands from formal testimony to all forms of falsehood.

The Proverbs wisdom tradition. Proverbs contains the densest concentration of truth/lie vocabulary in Scripture. Of seven things the LORD hates, two directly concern lying: "a lying tongue" and "a false witness that speaketh lies" (Pro 6:16-19). Lying lips are toebah (abomination) to the LORD (Pro 12:22). A false witness is compared to lethal weapons -- maul, sword, and sharp arrow (Pro 25:18). A faithful witness does not lie; a false witness breathes out lies (Pro 14:5). The lip of truth endures forever; a lying tongue is temporary (Pro 12:19). False witnesses will not go unpunished (Pro 19:5,9).

The legal framework. The Torah establishes procedural safeguards against false witness: two or three witnesses are required for capital cases (Num 35:30; Deu 17:6), and witnesses must cast the first stone (Deu 17:7), creating personal accountability. The false witness penalty is symmetric: the punishment intended for the victim is inflicted on the liar (Deu 19:18-19). A husband who falsely accuses his bride is flogged and fined (Deu 22:18-19). Withholding testimony when adjured is itself sinful (Lev 5:1). The legal system presupposes and depends upon truthful testimony.

The God-Satan antithesis. Scripture presents truth and falsehood as rooted in the natures of God and Satan respectively. God "cannot lie" (Tit 1:2). It is "impossible for God to lie" (Heb 6:18). "God is not a man, that he should lie" (Num 23:19). Christ identifies Himself as "the truth" (Jhn 14:6), and no guile was found in His mouth (1 Pe 2:22; Isa 53:9). By contrast, the devil "abode not in the truth, because there is no truth in him" (Jhn 8:44). When Satan speaks a lie, "he speaketh of his own" -- lying originates within his nature. He is "a liar, and the father of it." His very name, diabolos, means "slanderer" -- the embodiment of false witness. Murder and lying are identified as his twin characteristics from the beginning.

Jesus's teaching. Jesus treats the ninth commandment as authoritative, quoting it directly (Mat 19:18; Mrk 10:19). He locates false witness in the heart (Mat 15:19) alongside murder, adultery, and theft, indicating that all commandment violations are heart issues. He intensifies the truth standard: "let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil" (Mat 5:37). He extends accountability to "every idle word" (Mat 12:36). Jesus Himself was the victim of false witness at His trial (Mat 26:59-60), where the council sought pseudomarturia against Him to put Him to death -- the very commandment He taught was violated against Him.

The NT apostolic witness. Paul quotes Zechariah 8:16 in commanding believers to "speak every man truth with his neighbour" (Eph 4:25), grounding the command in the body of Christ: "we are members one of another." He prohibits lying in language that echoes Leviticus 19:11: "Lie not one to another" (Col 3:9), connecting it to having "put off the old man." His vice list in 1 Timothy 1:9-10 follows the Decalogue order, placing "liars" and "perjured persons" (9th commandment) after menstealers (8th). Peter quotes Psalm 34:13 directly (1 Pe 3:10), confirming continuity. John states that claiming to know God while not keeping His commandments makes one "a liar" (1 Jn 2:4). The death of Ananias and Sapphira (Act 5:1-10) demonstrates that lying to the Holy Spirit carries the severest consequences, even in the apostolic era.

The Rahab and midwives cases. These narratives describe situations where deception occurred alongside acts of faith and mercy. The Hebrew midwives feared God and refused to kill infants; God blessed them "because the midwives feared God" (Exo 1:21). Rahab is commended for her faith in receiving the spies (Heb 11:31) and for her works in receiving the messengers and sending them out safely (Jas 2:25). Neither the Hebrews passage nor the James passage mentions the lie. The biblical text commends faith and life-preservation. It does not commend, excuse, or create an exception for deception. The broader biblical testimony -- from the commandment itself through Proverbs, the prophets, Jesus, and Revelation -- uniformly condemns all forms of lying.

Eschatological consequences. Revelation pronounces a threefold judgment on liars. "All liars shall have their part in the lake which burneth with fire and brimstone" (Rev 21:8). Nothing that "maketh a lie" enters the New Jerusalem (Rev 21:27). "Without are...whosoever loveth and maketh a lie" (Rev 22:15). Conversely, the redeemed are characterized by truthfulness: "in their mouth was found no guile" (Rev 14:5), fulfilling Zephaniah's prophecy that the remnant "shall not speak lies" (Zep 3:13).

Cross-commandment connections. The ninth commandment connects to multiple other commandments: the 3rd (shav links God's name in vain to false witness; Lev 19:12 bridges false swearing and profaning God's name), the 6th (false witness leads to murder -- Jhn 8:44 pairs them; Pro 25:18 compares false witness to weapons; 1 Ki 21 demonstrates the sequence), the 8th (Lev 19:11 links stealing, dealing falsely, and lying; Pro 21:6 condemns lying for treasure), and the 1st/2nd (Rom 1:25 shows idolatry built on "the lie" of exchanging truth about God for falsehood).

The gathered evidence -- 49 new explicit statements (E521-E569) plus 17 also-in entries, 8 necessary implications (N078-N085), and 5 inferences (I046-I050, all I-A) -- consistently presents the ninth commandment as a prohibition that extends from formal legal testimony to all forms of falsehood, is grounded in the truthful character of God and opposed to the lying nature of Satan, is treated as authoritative from Genesis to Revelation, and carries ultimate eschatological consequences for those who love and practice lies.
