Leviticus 5:14-16

14And the Lord spake unto Moses, saying, 15If a soul commit a trespass, and sin through ignorance, in the holy things of the Lord; then he shall bring for his trespass unto 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 the fifth part thereto, and give it unto the priest: and the priest shall make an atonement for him with the ram of the trespass offering, and it shall be forgiven him.
