Leviticus 4:28-30

Living Bible

²⁸ But as soon as he does realize it, he is to bring as his sacrifice a female goat without defect to atone for his sin. ²⁹ He shall bring it to the place where the animals for burnt offerings are killed, and there lay his hand upon the head of the sin offering and kill it. ³⁰ And the priest shall take some of the blood with his finger and smear it upon the horns of the burnt offering altar. Then the priest shall pour out the remainder of the blood at the base of the altar.
