A false witness shall not be unpunished, and he that speaketh lies shall not escape.
– Proverbs 19:5
The word for unpunished means to be clear, or innocent. It has a judicial gloss here, since false witness has legal connotations. False witness is one of the hated abominations in Proverbs 6:16-19. The law forbids false witness and prescribes strict punishment for it (Exodus 20:16; 23:1; Deuteronomy 19:16). A false witness may go unchecked in this life, but this proverb promises he shall not escape (Revelation 21:8, 27; 22:15).
