Leviticus 5:1-2

Complete Jewish Bible

5 “‘If a person who is a witness, sworn to testify, sins by refusing to tell what he has seen or heard about the matter, he must bear the consequences. ² If a person touches something unclean, whether the carcass of an unclean wild animal, a domestic animal or a reptile, he is guilty, even though he may not be aware that he is unclean.
