Leviticus 4:23-25

New Revised Standard Version, Anglicised Catholic Edition

²³ once the sin that he has committed is made known to him, he shall bring as his offering a male goat without blemish. ²⁴ He shall lay his hand on the head of the goat; it shall be slaughtered at the spot where the burnt-offering is slaughtered before the Lord; it is a sin-offering. ²⁵ 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.
