Leviticus 5:1-2

JuliaSmith(i) 1 And when a soul shall sin, and he heard the voice of an oath, and he a witness, if he saw or knew; if he shall not announce, he bore his sin. 2 Or when a soul shall touch upon any unclean thing, if upon a carcase of an unclean beast, or upon the carcase of unclean cattle, or upon the carcase of an unclean creeping thing, and it was hidden from him: and he is unclean and guilty.
