Leviticus 5:7-10 - If You Cannot Afford A Sheep
7 But if he be not able to bring a sheep, then let him bring for his trespass which he hath sinned, two turtle doves or two young pigeons unto the LORD; one for a sin offering and another for a burnt offering. 8 And he shall bring them unto the priest, which shall offer the sin offering first and wring the neck asunder of it, but pluck it not clean off. 9 And let him sprinkle of the blood of the sin offering upon the side of the altar, and let the rest of the blood bleed upon the bottom of the altar, and then it is a sin offering. 10 And let him offer the second for a burnt offering as the manner is: and so shall the priest make an atonement for him for the sin which he hath sinned, and it shall be forgiven him.
