Numbers 19:13-16

¹³Whoever touches a dead person, the body of a man who has died, and doesn’t purify himself, defiles the LORD’s tabernacle; and that soul shall be cut off from Israel; because the water for impurity was not sprinkled on him, he shall be unclean. His uncleanness is yet on him.

¹⁴“This is the law when a man dies in a tent: everyone who comes into the tent, and everyone who is in the tent, shall be unclean seven days.

¹⁵Every open vessel, which has no covering bound on it, is unclean.

¹⁶“Whoever in the open field touches one who is slain with a sword, or a dead body, or a bone of a man, or a grave, shall be unclean seven days.
