Leviticus 5:16

And he shall make amends for the harm that he hath done in the holy thing, in neglecting to perform the services which were due to the Lord, and shall add the fifth part thereto, and give it unto the priest, as a penalty or forfeit for neglecting so important a duty toward the Lord; and the priest shall make an atonement for him with the ram of the trespass-offering, and it shall be forgiven him, the ceremony being performed as described in Leviticus 7-1-6.
