Leviticus 5:15-19

¹⁵If any one commit a trespass, and sin through error, in the holy things of the LORD, then he shall bring his forfeit unto the LORD, a ram without blemish out of the flock, according to thy valuation in silver by shekels, after the shekel of the sanctuary, for a guilt-offering.

¹⁶And 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 guilt-offering, and he shall be forgiven.

¹⁷And if any one sin, and do any of the things which the LORD hath commanded not to be done, though he know it not, yet is he guilty, and shall bear his iniquity.

¹⁸And he shall bring a ram without blemish out of the flock, according to thy valuation, for a guilt-offering, unto the priest; and the priest shall make atonement for him concerning the error which he committed, though he knew it not, and he shall be forgiven.

¹⁹It is a guilt-offering — he is certainly guilty before the LORD.
