Leviticus 5:5-8

⁵And it shall be that when (he knoweth that) he is guilty in one of these (things) he shall confess that he hath sinned thereby;

⁶And shall bring his sin offering before the Lord for the sin that he hath sinned; a she-lamb from the flock, or a kid of the goats, for a sin offering; and the priest shall atone for him and for his sin.

⁷But if his hands be not sufficient to offer a lamb, let him bring for the sin that he hath sinned two turtle doves, or two young pigeons before the Lord, one for the sin offering, and one for the burnt sacrifice.

⁸And he shall bring them to the priest, and he shall offer the sin offering first, and wring off its head near to the spine, but he shall not divide (the bird).
