Leviticus 4:33-34

Darby(i) 33 And he shall lay his hand on the head of the sin-offering, and slaughter it for a sin-offering at the place where they slaughter the burnt-offering. 34 And the priest shall take of the blood of the sin-offering with his finger, and put [it] on the horns of the altar of burnt-offering, and shall pour out all the blood thereof at the bottom of the altar.
