² Or if a nefesh touch anything tamei (unclean), whether it be a nivlat chayyah teme’ah (carcass of an unclean beast), or a nivlat behemah teme’ah (carcass of unclean livestock), or the nivlat sheretz tamei (carcass of unclean creeping things), and if it be hidden from him; he also shall be tamei, and guilty.

³ Or if he touch the tum’at adam (uncleanness of man), whatsoever tumah it be that a man shall be made unclean therewith, and it be hid from him; when he knoweth of it, then he shall be guilty.
