Leviticus 5:9 DBY

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.

¹¹  But if his hand cannot attain to two turtle-doves, or two young pigeons, then he that sinned shall bring for his offering the tenth part of an ephah of fine flour for a sin-offering: he shall put no oil on it, neither shall he put frankincense thereon; for it is a sin-offering.
