Leviticus 5:7-9

Darby Translation

⁷ And if his hand be not able to bring what is so much as a sheep, then he shall bring for his trespass which he hath sinned two turtle-doves or two young pigeons, to Jehovah; one for a sin-offering, and the other for a burnt-offering.

⁸ And he shall bring them unto the priest, who shall present that which is for the sin-offering first, and pinch off his head at the neck, but shall not divide it;

⁹ and he shall sprinkle of the blood of the sin-offering on the wall of the altar; and the rest of the blood shall be wrung out at the bottom of the altar: it is a sin-offering.
