Leviticus 5:4-6

MSTC(i) 4 Either when a soul sweareth: so that he pronounceth with his lips to do evil or to do good — whatsoever it be that a man pronounceth with an oath — and the thing be out of his mind and afterward cometh to the knowledge of it, then he hath offended in one of these. 5 Then when he hath sinned in one of these things, he shall confess that wherein that he hath sinned, 6 and shall bring his trespass offering unto the LORD for his sin which he hath sinned. A female from the flock, whether it be an ewe or a she goat, for a sin offering. And the priest shall make an atonement for him for his sin.
