Leviticus 5:2-6

²That soul which shall touch any unclean thing, or carcase, or that which is unclean being taken of beasts, or the dead bodies of abominable reptiles which are unclean, or carcases of unclean cattle,

³or should touch the uncleanness of a man, or whatever kind, which he may touch and be defiled by, and it should have escaped him, but afterwards he should know, —then he shall have transgressed.

⁴That unrighteous soul, which determines with his lips to do evil or to do good according to whatever a man may determine with an oath, and it shall have escaped his notice, and he shall afterwards know it, and so he should sin in some one of these things:

⁵—then shall he declare his sin in the tings wherein he has sinned by that sin.

⁶And he shall bring for his transgressions against the Lord, for his sin which he has sinned, a ewe lamb of the flock, or a kid of the goats, for a sin-offering; and the priest shall make an atonement for him for his sin which he has sinned, and his sin shall be forgiven him.
