Numbers 15:24-26

²⁴Then shall it be, if, through inadvertence of the congregation, it was committed by ignorance, that all the congregation shall prepare one young bullock for a burnt-offering, for a sweet savor unto the Lord, with his meat-offering, and his drink-offering, according to the prescribed manner, and one he-goat for a sin-offering.

²⁵And the priest shall make an atonement for all the congregation of the children of Israel, and it shall be forgiven unto them; for it is a sin of ignorance; and they have brought their offering, a sacrifice made by fire unto the Lord, and their sin-offering before the Lord, for their sin of ignorance:

²⁶And it shall be forgiven unto all the congregation of the children of Israel, and unto the stranger that sojourneth among them; for by all the people was it done in ignorance.
