Numbers 19:13-19

131Anyone who touches a dead body, the 2body of a person who has died, and does not purify himself, 3defiles the 4tabernacle of the Lord; and that person shall be cut off from Israel. Since the water for impurity was not 5sprinkled on him, he will be unclean; his uncleanness is still on him.

14‘This is the law when a person dies in a tent: everyone who comes into the tent and everyone who is in the tent will be unclean for seven days. 15And every open container, which has no cover tied down on it, will be unclean. 166Also, anyone who in the open field touches one who has been killed with a sword or one who has died naturally, or touches a human bone or a grave, will be unclean for seven days. 17Then for the unclean person they shall take some of the 7ashes of the 8burnt 910purification from sin and 11running water shall be 12added to them in a container. 18And a clean person shall take hyssop and dip it in the water, and sprinkle it on the tent, on all the furnishings, on the persons who were there, and on the one who touched the bone or the one who was killed or the one who died naturally, or the grave. 19Then the clean person 13shall sprinkle on the unclean on the third day and on the seventh day; and on the seventh day he shall purify him, and he shall wash his clothes and bathe himself in water and will be clean by evening.
