Leviticus 5:4-6

NHEB(i) 4 "'Or if anyone swears rashly with his lips to do evil, or to do good, whatever it is that a man might utter rashly with an oath, and it is hidden from him; when he knows of it, then he shall be guilty of one of these. 5 It shall be, when he is guilty of one of these, he shall confess that in which he has sinned: 6 and he shall bring his trespass offering to the 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 concerning his sin.
