Leviticus 5:17-19 - Unknown Trespass
17 "When a soul sinneth and committeth any of these things which are forbidden to be done by the commandments of the LORD: though he wist it not, he hath yet offended and is in sin, 18 and shall bring a ram without blemish out of the flock that is esteemed to be worth a sin offering, unto the priest. And the priest shall make an atonement for him for the ignorance which he did, and was not ware, and it shall be forgiven him. 19 This is a trespass offering, for he trespassed against the LORD."
