Numbers 15:26

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 savor 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.
