Leviticus 5:16-18

New Revised Standard Version Catholic Edition

¹⁶ And you shall make restitution for the holy thing in which you were remiss, and shall add one-fifth to it and give it to the priest. The priest shall make atonement on your behalf with the ram of the guilt offering, and you shall be forgiven.

¹⁷ If any of you sin without knowing it, doing any of the things that by the Lord’s commandments ought not to be done, you have incurred guilt, and are subject to punishment. ¹⁸ You shall bring to the priest a ram without blemish from the flock, or the equivalent, as a guilt offering; and the priest shall make atonement on your behalf for the error that you committed unintentionally, and you shall be forgiven.
