Numbers 19:7–10

7 Then the priest rshall wash his clothes and bathe his body in water, and afterward he may come into the camp. But the priest shall be unclean until evening. 8 sThe one who burns the heifer rshall wash his clothes in water and bathe his body in water and shall be unclean until evening. 9 And a man who is clean shall gather up tthe ashes of the heifer and deposit them outside the camp in a uclean place. And they shall be kept for the water for vimpurity for the congregation of the people of Israel; it is a sin offering. 10 And the one who gathers the ashes of the heifer rshall wash his clothes and be unclean until evening. And this shall be a perpetual statute for the people of Israel, and for the stranger who sojourns among them.
