Leviticus 5:6–10

6  and he shall bring his trespass-offering to Jehovah for his sin which he hath sinned, a female from the small cattle, a sheep or doe goat, for a sin-offering; and the priest shall make atonement for him to cleanse him from his sin.

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. 10  And he shall offer the other for a burnt-offering, according to the ordinance. And the priest shall make atonement for him to cleanse him from his sin which he hath sinned, and it shall be forgiven him.
