Leviticus 5:4-6

American Standard Version

⁴ Or if any one swear rashly with his lips to do evil, or to do good, whatsoever it be that a man shall utter rashly with an oath, and it be hid from him; when he knoweth of it, then he shall be guilty in one of these things. ⁵ And it shall be, when he shall be guilty in one of these things, that he shall confess that wherein he hath sinned: ⁶ and he shall bring ^[a]his trespass-offering unto Jehovah for his sin which he hath 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.
