Leviticus 5:4-6

New American Standard Bible

⁴ Or if a person ^(A)swears thoughtlessly with his lips to do evil or to do good, in whatever matter people speak thoughtlessly with an oath, and it is hidden from him, and then he comes to know it, he will be guilty of one of these things. ⁵ So it shall be when he becomes guilty of one of these things, that he shall ^(B)confess that in which he has sinned. ⁶ He shall also bring his guilt offering to the Lord for his sin which he has ^[a]committed, ^(C)a female from the flock, a lamb or a ^[b]goat as a sin offering. So the priest shall make atonement on his behalf for his sin.
