Numbers 15:25-27

²⁵And the priest shall make atonement for all the congregation of the children of Israel, and the trespass shall be forgiven them, because it is involuntary; and they have brought their gift, a burnt offering to the Lord for their trespass before the Lord, even for their involuntary sins.

²⁶And it shall be forgiven as respects all the congregation of the children of Israel, and the stranger that is dwelling among you, because it is involuntary to all the people.

²⁷And if one soul sin unwillingly, he shall bring one she-goat of a year old for a sin-offering.
