A false witness shall not be unpunished, and he that speaketh lies shall not escape.

King James Translators' Notes

unpunished: Heb. held innocent

Jamieson-Fausset-Brown Bible Commentary

5. Compare Pr 19:9, where perish explains not escape here (compare Ps 88:9, 10).

Matthew Henry's Concise Commentary

19:3. Men run into troubles by their own folly, and then fret at the appointments of God. 4. Here we may see how strong is men's love of money. 5. Those that tell lies in discourse, are in a fair way to be guilty of bearing false-witness. 6. We are without excuse if we do not love God with all our hearts. His gifts to us are past number, and all the gifts of men to us are fruits of his bounty. 7. Christ was left by all his disciples; but the Father was with him. It encourages our faith that he had so large an experience of the sorrows of poverty. 8. Those only love their souls aright that get true wisdom. 9. Lying is a damning, destroying sin. 10. A man that has not wisdom and grace, has no right or title to true joy. It is very unseemly for one who is a servant to sin, to oppress God's free-men.

Matthew Henry's Whole Bible Commentary

Verse 5

Here we have, 1. The sins threatened-bearing false witness in judgment and speaking lies in common conversation. Men could not arrive at such a pitch of impiety as to bear false witness (where to the guilt of a lie is added that of perjury and injury) if they had not advanced to it by allowing themselves to speak untruths in jest and banter, or under pretence of doing good. Thus men teach their tongues to speak lies, Jer. 9:5. Those that will take a liberty to tell lies in discourse are in a fair way to be guilty of the greater wickedness of false-witness-bearing, whenever they are tempted to it, though they seemed to detest it. Those that can swallow a false word debauch their consciences, so that a false oath will not choke them. 2. The threatening itself: They shall not go unpunished; they shall not escape. This intimates that that which emboldens them in the sin is the hope of impunity, it being a sin which commonly escapes punishment from men, though the law is strict, Deu. 19:18, 19. But it shall not escape the righteous judgment of God, who is jealous, and will not suffer his name to be profaned; we know where all liars will have their everlasting portion.
