Numbers 19:7-9

Revised Standard Version

⁷ Then the priest shall wash his clothes and bathe his body in water, and afterwards he shall come into the camp; and the priest shall be unclean until evening. ⁸ He who burns the heifer shall 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 the ashes of the heifer, and deposit them outside the camp in a clean place; and they shall be kept for the congregation of the people of Israel for the water for impurity, for the removal of sin.
