Proverbs 21:28

A false witness Hebrew, עד כזבים, A witness of lies; one who is forward to swear or speak false things, or such things as he hath neither heard nor seen, but devised in his own heart; shall perish Shall be severely punished, either by God or men, and shall be confounded and silenced, because none will for the future regard or credit his testimony. But the man that heareth Before he speaks, and witnesseth nothing but what he has heard or seen, and knows to be true; speaketh constantly

Doth not contradict himself, but always affirms the same thing. Or, as most interpreters render לנצח ידבר, speaketh, or may, or shall speak for ever. He dare speak freely and boldly; and, when liars are cut off, he lives, and is in a capacity of speaking and bearing witness again and again, as occasion requires, as long as he lives, and his testimony will be received.
