Leviticus 5:2-4

American Standard Version

² Or if any one touch any unclean thing, whether it be the carcass of an unclean beast, or the carcass of unclean cattle, or the carcass of unclean creeping things, and it be hidden from him, and he be unclean, then he shall be guilty. ³ Or if he touch the uncleanness of man, whatsoever his uncleanness be wherewith he is unclean, and it be hid from him; when he knoweth of it, then he shall be guilty. 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.
