Leviticus 5:1-2

Darby Translation

5 And if any one sin, and hear the voice of adjuration, and he is a witness whether he hath seen or known [it], if he do not give information, then he shall bear his iniquity.

² Or if any one touch any unclean thing, whether it be the carcase of an unclean beast, or the carcase of unclean cattle, or the carcase of an unclean crawling thing, and it be hid from him,—he also is unclean and guilty;
