Numbers 15:24-26

24 then if it was done unintentionally a without the knowledge of the congregation, all the congregation shall offer one bull from the herd for a burnt offering, a pleasing aroma to the  Lord, b with its grain offering and its drink offering, according to the rule, and c one male goat for a sin offering. 25  d And the priest shall make atonement for all the congregation of the people of Israel, and they shall be forgiven, because it was a mistake, and they have brought their offering, a food offering to the  Lord, and their sin offering before the  Lord for their mistake. 26 And all the congregation of the people of Israel shall be forgiven, and the stranger who sojourns among them, because the whole population was involved in the mistake.
