Leviticus 5:6-8

Modern English Version

⁶ And he shall bring his guilt offering to the Lord for his sin which he has committed, a female from the flock, a lamb or goat, for a sin offering. And the priest shall make atonement for him concerning his sin.

⁷ If he cannot afford an animal, then he shall bring for his guilt offering, on account of the sin that he committed, two turtledoves or two pigeons to the Lord, one for a sin offering and one for a burnt offering. ⁸ He shall bring them to the priest who shall offer the one for the sin offering first. He will wring off its head at its neck, but he shall not sever it.
