Leviticus 5:16-18

NHEB(i) 16 He shall make restitution for that which he has done wrong in the holy thing, and shall add a fifth part to it, and give it to the priest; and the priest shall make atonement for him with the ram of the trespass offering, and he will be forgiven. 17 "If anyone sins, and does any of the things which the LORD has commanded not to be done; though he did not know it, yet he is guilty, and shall bear his iniquity. 18 He shall bring a ram without blemish from of the flock, according to your estimation, for a trespass offering, to the priest; and the priest shall make atonement for him concerning the thing in which he sinned and did not know it, and he will be forgiven.
