Numbers 15:24-26

²⁴then it shall come to pass, if a trespass be committed unwillingly, unknown to the congregation, then shall all the congregation offer a calf of the herd without blemish for a whole-burnt-offering of sweet savour to the Lord, and its meat-offering and its drink-offering according to the ordinance, and one kid of the goats for a sin-offering.

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 abiding among you, because it is involuntary to all the people.
