Leviticus 4:23-25

²³and his trespass wherein he has sinned, be known to him, then shall he offer for his gift a kid of the goats, a male without blemish.

²⁴And he shall lay his hand on the head of the kid, and they shall kill it in the place where they kill the victims for whole burnt offerings before the Lord; it is a sin-offering.

²⁵And the priest shall put some of the blood of the sin-offering with his finger on the horns of the altar of whole burnt offering; and he shall pour out all its blood by the bottom of the altar of whole burnt offerings.
