Leviticus 5:1-5

1“When someone sins in any of these ways: If he has seen, heard, or known about something he has witnessed, and did not respond to a public call to testify, he will bear his iniquity.

2Or if someone touches anything unclean  — a carcass of an unclean wild animal, or unclean livestock, or an unclean swarming creature  — without being aware of it, he is unclean and incurs guilt.

3Or if he touches human uncleanness  — any uncleanness by which one can become defiled  — without being aware of it, but later recognizes it, he incurs guilt.

4Or if someone swears rashly to do what is good or evil — concerning anything a person may speak rashly in an oath — without being aware of it, but later recognizes it, he incurs guilt in such an instance.

5If someone incurs guilt in one of these cases, he is to confess he has committed that sin.
