Numbers 15:24-25

24and if it was done unintentionally without the community’s awareness, the entire community is to prepare one young bull for a burnt offering as a pleasing aroma to the Lord, with its grain offering and drink offering according to the regulation, and one male goat as a sin offering.

25The priest will then make atonement for the entire Israelite community so that they may be forgiven, for the sin was unintentional. They are to bring their offering, a food offering to the Lord, and their sin offering before the Lord for their unintentional sin.
