Leviticus 5:17-19 - Unknown Trespass

¹⁷ And if a soul sins, and he has done that which ought not to be done, any one from all the commands of Jehovah, and does not know, and he is guilty and bears his iniquity; ¹⁸ then he shall bring a ram without blemish out of the flock, at your evaluation, for a trespass offering, to the priest. And the priest shall make an atonement for him for his ignorance in which he erred without knowing it, and it shall be forgiven him. ¹⁹ It is a trespass offering. He has certainly trespassed against Jehovah.
