Leviticus 5:4-5

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.
