Leviticus 5:17-19 - Unknown Trespass

¹⁷ And if a soul sins, and commits any of these things which are forbidden to be done by the commandments of the LORD; though he knew it not, yet is he guilty, and shall bear his iniquity. ¹⁸ And he shall bring a ram without blemish out of the flock, with your valuation, for a trespass offering, unto the priest: and the priest shall make an atonement for him concerning his ignorance wherein he erred and knew it not, and it shall be forgiven him. ¹⁹ It is a trespass offering: he has certainly trespassed against the LORD.
