Leviticus 5:3-5

Amplified Bible, Classic Edition

³ Or if he touches human uncleanness, of whatever kind the uncleanness may be with which he becomes defiled, and he is unaware of it, when he does know it, then he shall be guilty.

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.
