Leviticus 5:17-19 - Unknown Trespass
17 And if a soul sins, and does any of the things which LORD has commanded not to be done, though he did not know it, yet he is guilty, and shall bear his iniquity. 18 And he shall bring a ram without blemish out of the flock, according to thy estimation, for a trespass-offering, to the priest. And the priest shall make atonement for him concerning the thing by which he erred unwittingly and knew 19 It is a trespass-offering. He is certainly guilty before LORD.
