Leviticus 5:6-8

Darby Translation

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;
