Leviticus 5:9-11

Darby Translation

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.
