Leviticus 6:4-7

4Then it shall be, because he hath sinned, and is guilty, that he shall restore that which he took violently away, or the thing which he hath deceitfully gotten, or that which was delivered him to keep, or the lost thing which he found,

5Or all that about which he hath sworn falsely; he shall even restore it in the principal, and shall add the fifth part more thereto, and give it unto him to whom it appertaineth, in the day of his trespass offering.1

6And he shall bring his trespass offering unto Yhwh, a ram without blemish out of the flock, with thy estimation, for a trespass offering, unto the priest:

7And the priest shall make an atonement for him before Yhwh: and it shall be forgiven him for any thing of all that he hath done in trespassing therein.
