Leviticus 5:1-3

Living Bible

5 “Anyone refusing to give testimony concerning what he knows about a crime is guilty.

² “Anyone touching anything ceremonially unclean—such as the dead body of an animal forbidden for food, wild or domesticated, or the dead body of some forbidden insect—is guilty, even though he wasn’t aware of touching it. ³ Or if he touches human discharge of any kind, he becomes guilty as soon as he realizes that he has touched it.
