Leviticus 5:7-13

“But if you cannot afford to bring a sheep, you may bring to the LORD two turtledoves or two young pigeons as the penalty for your sin. One of the birds will be for a sin offering, and the other for a burnt offering. You must bring them to the priest, who will present the first bird as the sin offering. He will wring its neck but without severing its head from the body. Then he will sprinkle some of the blood of the sin offering against the sides of the altar, and the rest of the blood will be drained out at the base of the altar. This is an offering for sin. The priest will then prepare the second bird as a burnt offering, following all the procedures that have been prescribed. Through this process the priest will purify you from your sin, making you right with the LORD, and you will be forgiven. “If you cannot afford to bring two turtledoves or two young pigeons, you may bring two quarts of choice flour for your sin offering. Since it is an offering for sin, you must not moisten it with olive oil or put any frankincense on it. Take the flour to the priest, who will scoop out a handful as a representative portion. He will burn it on the altar on top of the special gifts presented to the LORD. It is an offering for sin. Through this process, the priest will purify those who are guilty of any of these sins, making them right with the LORD, and they will be forgiven. The rest of the flour will belong to the priest, just as with the grain offering.”
