Leviticus 5:4-6

ACV(i) 4 Or if a soul swears rashly with his lips to do evil, or to do good, whatever it be that a man shall utter rashly with an oath, and it be hid from him, when he realizes it, then he shall be guilty in one of these. 5 And it shall be, when he shall be guilty in one of these, that he shall confess that by which he has sinned. 6 And he shall bring his trespass offering to LORD for his sin which he has sinned, a female from the flock, a lamb or a goat, for a sin offering. And the priest shall make atonement for him as concerning his sin.
