Leviticus 4:21

18 He is to put some of the blood on the horns of the altar that is before the Lord in the tent of meeting. The rest of the blood he shall pour out at the base of the altar of burnt offering at the entrance to the tent of meeting. 19 He shall remove all the fat from it and burn it on the altar, 20 and do with this bull just as he did with the bull for the sin offering. In this way the priest will make atonement for the community, and they will be forgiven. 21 Then he shall take the bull outside the camp and burn it as he burned the first bull. This is the sin offering for the community.

22 “ ‘When a leader sins unintentionally and does what is forbidden in any of the commands of the Lord his God, when he realizes his guilt 23 and the sin he has committed becomes known, he must bring as his offering a male goat without defect. 24 He is to lay his hand on the goat’s head and slaughter it at the place where the burnt offering is slaughtered before the Lord. It is a sin offering.
