Numbers 15:25-27

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

²⁶And it shall be forgiven all the congregation of the children of Israel, and the stranger that sojourneth among them; seeing all the people were in ignorance.

²⁷And if any soul shall sin through ignorance, then he shall bring a she-goat of the first year for a sin-offering.
