Leviticus 5:7-11

⁷If you can't afford a lamb, you may offer to the Lord as compensation for your sin two turtledoves or two young pigeons, one as a sin offering and one as a burnt offering.

⁸You are to take them to the priest, who shall present the first one as the sin offering. He is to wring its head from the neck without removing it completely.

⁹Then he is to sprinkle some of the blood of the sin offering on the side of the altar while the rest of the blood is poured out at the bottom of the altar. It is a sin offering.

¹⁰The priest must then prepare the second bird as a burnt offering according to the regulations. In this way the priest will make you right for your sin, and you will be forgiven.

¹¹If you can't afford two turtledoves or two young pigeons you may bring a tenth of an ephah of the best flour as a sin offering. Don't put olive oil or frankincense on it, because it is a sin offering.
