Leviticus 5:14-19

14And the LORD spoke to Moses, saying, 15If a soul shall commit a trespass, and sin through ignorance, in the holy things of the LORD; then he shall bring for his trespass to the LORD a ram without blemish out of the flocks, with thy estimation by shekels of silver, after the shekel of the sanctuary, for a trespass offering: 16And he shall make amends for the harm that he hath done in the holy thing, and shall add to it the fifth part, and give it to the priest: and the priest shall make an atonement for him with the ram of the trespass offering, and it shall be forgiven him. 17And if a soul shall sin, and commit any of these things which are forbidden to be done by the commandments of the LORD; though he knew it not, yet is he guilty, and shall bear his iniquity. 18And he shall bring a ram without blemish out of the flock, with thy estimation, for a trespass offering, to the priest: and the priest shall make an atonement for him concerning his ignorance in which he erred and knew it not, and it shall be forgiven him. 19It is a trespass offering: he hath certainly trespassed against the LORD.
