Numbers 19:13-19

13Anyone who touches the corpse of any dead person and does not purify himself defiles the tabernacle of the Lord. And that person must be cut off from Israel, because the water of purification was not sprinkled on him. He will be unclean; his uncleanness remains on him.

14“‘This is the law: When a man dies in a tent, anyone who comes into the tent and all who are in the tent will be ceremonially unclean seven days.

15And every open container that has no covering fastened on it is unclean.

16And whoever touches the body of someone killed with a sword in the open fields, or the body of someone who died of natural causes, or a human bone, or a grave, will be unclean seven days.

17“‘For a ceremonially unclean person you must take some of the ashes of the heifer burnt for purification from sin and pour fresh running water over them in a vessel.

18Then a ceremonially clean person must take hyssop, dip it in the water, and sprinkle it on the tent, on all its furnishings, and on the people who were there, or on the one who touched a bone, or one killed, or one who died, or a grave.

19And the clean person must sprinkle the unclean on the third day and on the seventh day; and on the seventh day he must purify him, and then he must wash his clothes, and bathe in water, and he will be clean in the evening.
