Leviticus 5:17-19 - Unknown Trespass

¹⁷ "If anyone sins, and does any of the things which Yahweh has commanded not to be done; though he didn't 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 didn't know it, and he will be forgiven. ¹⁹ It is a trespass offering. He is certainly guilty before Yahweh."
