Numbers 19:11; Numbers 19:13; Numbers 19:16

11 "Whoever touches the dead body of any person shall be unclean seven days.

13 Whoever touches a dead person, the body of anyone who has died, and does not cleanse himself, defiles the tabernacle of the LORD, and that person shall be cut off from Israel; because the water for impurity was not thrown on him, he shall be unclean. His uncleanness is still on him.

16 Whoever in the open field touches someone who was killed with a sword or who died naturally, or touches a human bone or a grave, shall be unclean seven days.
