Leviticus 4:22-26

²²"When a ruler sins, doing unwittingly any one of all the things which the LORD his God has commanded not to be done, and is guilty, ²³if 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 upon 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.
