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

A false witness shall not be unpunished; And he that uttereth lies shall perish.

A false witness shall not be held innocent, and he that uttereth lies shall perish.

A false witness is not acquitted, And whoso breatheth out lies perisheth.

A false witness shall not be unpunished; And he that breatheth forth lies shall perish.

A false witness shall not go unpunished. And whoever speaks lies will perish.

A false witness shall not be unpunished,.... See Gill on Proverbs 19:5;
and he that speaketh lies shall perish; or "be lost", shall be undone for ever; he shall not enter into the holy city, but have his part in the lake of fire: they that speak lies in hypocrisy, doctrinal ones, and are given up to believe and profess them, such shall be damned, 2-Thessalonians 2:11.

Lying is a damning, destroying sin.

The group of proverbs (Proverbs 19:9-16) now following begins and closes in the same way as the preceding.

And one who breathes out lies perisheth,
or goeth to ruin, for אבד (R. בד, to divide, separate) signifies to lose oneself in the place of the separated, the dead (Arab. in the infinite). In Proverbs 19:5, instead of this ἀπολεῖται (lxx), the negative οὐ σωθήσεται is used, or as the lxx there more accurately renders it, οὐ διαφεύξεται.
