Leviticus 5:14-19

And Jehovah spake unto Moses, saying, If any one commit a trespass, and sin unwittingly, in the holy things of Jehovah; then he shall bring his trespass-offering unto Jehovah, a ram without blemish out of the flock, according to thy estimation in silver by shekels, after the shekel of the sanctuary, for a trespass-offering: and he shall make restitution for that which he hath done amiss in the holy thing, and shall add the fifth part thereto, and give it unto the priest; and the priest shall make atonement for him with the ram of the trespass-offering, and he shall be forgiven. And if any one sin, and do any of the things which Jehovah hath commanded not to be done; though he knew it not, yet is he guilty, and shall bear his iniquity. And he shall bring a ram without blemish out of the flock, according to thy estimation, for a trespass-offering, unto the priest; and the priest shall make atonement for him concerning the thing wherein he erred unwittingly and knew it not, and he shall be forgiven. It is a trespass-offering: he is certainly guilty before Jehovah.
