Leviticus 5:1 Lev. 5:1
And if a soul sin, and hear the voice of swearing, and is a witness, whether he hath seen or known of it; if he do not utter it, then he shall bear his iniquity.
Proverbs 29:24 Prov. 29:24
Whoso is partner with a thief hateth his own soul: he heareth cursing, and bewrayeth it not.
