Leviticus 5:3-7

³Or if he shall touch the uncleanness of man, whatever uncleanness it may be that a man shall be defiled with, and it be hid from him; when he knoweth of it , then he shall be guilty.

⁴Or if a soul shall swear, pronouncing with his lips to do evil, or to do good, whatever it may be , that a man shall pronounce with an oath, and it be hid from him; when he knoweth of it , then he shall be guilty in one of these.

⁵And it shall be, when he shall be guilty in one of these things , that he shall confess that he hath sinned in that thing :

⁶And he shall bring his trespass-offering to the LORD for his sin which he hath sinned, a female from the flock, a lamb or a kid of the goats, for a sin-offering; and the priest shall make an atonement for him concerning his sin.

⁷And if he shall not be able to bring a lamb, then he shall bring for his trespass which he hath committed, two turtle-doves, or two young pigeons, to the LORD; one for a sin-offering, and the other for a burnt-offering.
