Numbers 15:22-29 - Laws About Unintentional Sins
22 If ye oversee yourselves and observe not all these commandments which the LORD hath spoken unto Moses, 23 and all that the LORD hath commanded you by the hand of Moses, from the first day forward that the LORD commanded among your generation: 24 when ought is committed ignorantly before the eyes of the congregation, then all the multitude shall offer a calf for a burnt offering to be a sweet savour unto the LORD, and the meat offering and the drink offering thereto, according to the manner: and a he-goat for a sin offering. 25 And the priest shall make an atonement for all the multitude of the children of Israel, and it shall be forgiven them, for it was ignorance. And they shall bring their gifts unto the offering of the LORD, and their sin offering before the LORD for their ignorance. 26 And it shall be forgiven unto all the multitude of the children of Israel, and unto the stranger that dwelleth among you: for the ignorance pertaineth unto all the people.
27 If any one soul sin through ignorance he shall bring a she-goat of a year old for a sin offering. 28 And the priest shall make an atonement for the soul that sinned ignorantly with the sin offering before the LORD and reconcile him, and it shall be forgiven him. 29 And both thou that art born one of the children of Israel and the stranger that dwelleth among you shall have both one law, if ye sin through ignorance.
