Leviticus 5:7-10 - If You Cannot Afford A Sheep

⁷ And if his hand shall not reach the sufficiency of a sheep, and he brought his trespass which he sinned, two turtledoves, or two sons of a dove, to Jehovah; one for the sin, and one for the burnt-offering. ⁸ And he brought them to the priest, and he brought near that for the sin first, and broke off its head from the front of its neck; and he shall not divide. ⁹ And he sprinkled from the blood of the sin upon the wall of the altar; and that remaining of the blood he shall press out at the foundation of the altar: it is sin. ¹⁰ And the second he shall make a burnt-offering according to the judgment: and the priest expiated for him from his sin which he sinned, and it was forgiven to him.
