Numbers 19:7-9

21st Century King James Version

⁷ Then the priest shall wash his clothes, and he shall bathe his flesh in water; and afterward he shall come into the camp, and the priest shall be unclean until the evening.

⁸ And he that burneth her shall wash his clothes in water and bathe his flesh in water, and shall be unclean until the evening.

⁹ And a man who is clean shall gather up the ashes of the heifer and lay them up outside the camp in a clean place, and it shall be kept for the congregation of the children of Israel for a water of separation: it is a purification for sin.
