Numbers 19:17-22

17Then for the unclean person they shall take some of the 1ashes of the 2burnt 34purification from sin and 5running water shall be 6added 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 7shall 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.

20‘But the person who is unclean and does not purify himself, that person shall be cut off from the midst of the assembly, because he has 8defiled the sanctuary of the Lord; the water for impurity has not been sprinkled on him, so he is unclean. 21So it shall be a permanent statute for them. And the one 9who sprinkles the water for impurity shall wash his clothes, and the one who touches the water for impurity will be unclean until evening. 2210Furthermore, anything that the unclean person touches will be unclean; and the person who touches it will be unclean until evening.’”
