Leviticus 5:3

1 “If someone sins by failing to testify when he hears a public charge about something he has witnessed, whether he has seen it or learned of it, he shall bear the iniquity.

2 Or if a person touches anything unclean—whether the carcass of any unclean wild animal or livestock or crawling creature—even if he is unaware of it, he is unclean and guilty.

3 Or if he touches human uncleanness—anything by which one becomes unclean—even if he is unaware of it, when he realizes it, he is guilty.

4 Or if someone swears thoughtlessly with his lips to do anything good or evil—in whatever matter a man may rashly pronounce an oath—even if he is unaware of it, when he realizes it, he is guilty in the matter.

5 If someone incurs guilt in one of these ways, he must confess the sin he has committed,

6 and he must bring his guilt offering to the LORD for the sin he has committed: a female lamb or goat from the flock as a sin offering. And the priest will make atonement for him concerning his sin.

7 If, however, he cannot afford a lamb, he may bring to the LORD as restitution for his sin two turtledoves or two young pigeons—one as a sin offering and the other as a burnt offering.
