Leviticus 4:22-26

22“When a leader sins and unintentionally violates any of the commands of the Lord his God by doing what is prohibited, and incurs guilt,

23or someone informs him about the sin he has committed, he is to bring an unblemished male goat as his offering.

24He is to lay his hand on the head of the goat and slaughter it at the place where the burnt offering is slaughtered before the Lord. It is a sin offering.

25Then the priest is to take some of the blood from the sin offering with his finger and apply it to the horns of the altar of burnt offering. The rest of its blood he is to pour out at the base of the altar of burnt offering.

26He must burn all its fat on the altar, like the fat of the fellowship sacrifice. In this way the priest will make atonement on his behalf for that person’s sin, and he will be forgiven.
