Also, anyone who in the open field touches one who has been slain with a sword or who has died naturally, or a human bone or a grave, shall be unclean for seven days.
Anyone who touches a corpse, the body of a man who has died, and does not purify himself, defiles the tabernacle of the Lord; and that person shall be cut off from Israel. Because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is still on him.
