Leviticus 5:4-6

Revised Standard Version

⁴ Or if any one utters with his lips a rash oath to do evil or to do good, any sort of rash oath that men swear, and it is hidden from him, when he comes to know it he shall in any of these be guilty. ⁵ When a man is guilty in any of these, he shall confess the sin he has committed, ⁶ and he shall bring his guilt offering to the Lord for the sin which he has committed, a female from the flock, a lamb or a goat, for a sin offering; and the priest shall make atonement for him for his sin.
