Leviticus 5:8-10

Amplified Bible, Classic Edition

⁸ He shall bring them to the priest, who shall offer the one for the sin offering first, and wring its head from its neck, but shall not sever it;

⁹ And he shall sprinkle some of the blood of the sin offering on the side of the altar, and the rest of the blood shall be drained out at the base of the altar; it is a sin offering.

¹⁰ And he shall prepare the second bird for a burnt offering, according to the ordinance; and the priest shall make atonement for him for his sin which he has committed, and he shall be forgiven.
