Leviticus 5:7-10 - If You Cannot Afford A Sheep
7 And if his means is not sufficient for a lamb, then he shall bring his trespass-offering for that by which he has sinned, two turtle-doves, or two young pigeons, to LORD, one for a sin-offering, and the other for a burnt-offering. 8 And he shall bring them to the priest, who shall offer that which is for the sin-offering first, and wring off its head from its neck, but shall not divide it apart. 9 And he shall sprinkle of the blood of the sin-offering upon the side of the altar, and the rest of the blood shall be drained out at the base of the altar. It is a sin-offering. 10 And he shall offer the second for a burnt-offering, according to the ordinance. And the priest shall make atonement for him as concerning his sin which he has sinned, and he shall be forgiven.
