How does Genesis 20:10 connect with the commandment against bearing false witness? Setting the Scene Genesis 20 recounts Abraham’s stay in Gerar. Fearful for his life, he tells the Philistine king, Abimelech, that Sarah is his sister. Abimelech takes her into his household, only to be warned by God in a dream. Confronted, Abraham admits the half-truth. Verse 10 captures the king’s astonishment: “Abimelech also asked Abraham, ‘What prompted you to do this?’” (Genesis 20:10) The Heart of the Matter • Abraham’s answer (vv. 11–13) reveals a mix of fear, self-interest, and rationalization. • Though Sarah was indeed his half-sister (v. 12), presenting her as solely his sister concealed their marriage—an intentional omission that misled others. • Scripture treats this as sin because it deceived Abimelech and endangered his household (vv. 3–9). Link to the Ninth Commandment “You shall not bear false witness against your neighbor.” (Exodus 20:16) • False witness is broader than courtroom perjury; it includes any distortion that harms another’s well-being or reputation (cf. Proverbs 12:22; Ephesians 4:25). • Abraham’s deception put Abimelech in jeopardy of unwitting adultery and divine judgment—clear harm to a “neighbor.” • Thus Genesis 20:10 shows a real-life example of the very behavior later forbidden at Sinai. Scripture Interprets Scripture • Psalm 34:13: “Keep your tongue from evil and your lips from deceitful speech.” • Colossians 3:9: “Do not lie to one another, since you have taken off the old self with its practices.” • Revelation 21:8 warns that “all liars” face judgment, underscoring the seriousness God places on truthfulness. Lessons to Take Home • Fear never justifies bending the truth; God can protect without our manipulation (cf. Isaiah 41:10). • Half-truths that create false impressions still violate God’s standard. • Our words carry real consequences for others; guarding them honors both God and neighbor. • Integrity builds trust with believers and unbelievers alike, showcasing the transforming power of faithful obedience. |
