Leviticus 5:2-3

JuliaSmith(i) 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. 3 Or when he shall touch upon the uncleanness of man, for all uncleanness which he shall be unclean in it, and it was hidden from him; and he shall know, and be guilty.
