Leviticus 5:1-3

Revised Standard Version Catholic Edition

5 “If any one sins in that he hears a public adjuration to testify and though he is a witness, whether he has seen or come to know the matter, yet does not speak, he shall bear his inquity. ² Or if any one touches an unclean thing, whether the carcass of an unclean beast or a carcass of unclean cattle or a carcass of unclean swarming things, and it is hidden from him, and he has become unclean, he shall be guilty. ³ Or if he touches human uncleanness, of whatever sort the uncleanness may be with which one becomes unclean, and it is hidden from him, when he comes to know it he shall be guilty.
