Leviticus 5:4-6

Amplified Bible, Classic Edition

⁴ Or if anyone unthinkingly swears he will do something, whether to do evil or good, whatever it may be that a man shall pronounce rashly taking an oath, then, when he becomes aware of it, he shall be guilty in either of these.^(A)

⁵ When a man is guilty in one of these, he shall confess the sin he has committed.

⁶ He shall bring his guilt or trespass offering to the Lord for the sin which he has committed, a female from the flock, a lamb or a goat, for a sin offering; and the priest shall make atonement for his sin.
