Leviticus 4:22-26

22"When a leader sins, doing unintentionally any one of all the things that by the commandments of the Lord his God ought not to be done, and realizes his guilt,

23or the sin which he has committed is made known to him, he shall bring as his offering a goat, a male without blemish,

24and shall lay his hand on the head of the goat and kill it in the place where they kill the burnt offering before the Lord; it is a sin offering.

25Then the priest shall take some of the blood of the sin offering with his finger and put it on the horns of the altar of burnt offering and pour out the rest of its blood at the base of the altar of burnt offering.

26And all its fat he shall burn on the altar, like the fat of the sacrifice of peace offerings. So the priest shall make atonement for him for his sin, and he shall be forgiven.
