Numbers 19:8-10

Living Bible

⁸ And the one who burns the animal must wash his clothes and bathe, and he too shall be defiled until evening. ⁹ Then someone who is not ceremonially defiled shall gather up the ashes of the heifer and place them in some purified place outside the camp, where they shall be kept for the people of Israel as a source of water for the purification ceremonies, for removal of sin. ¹⁰ And the one who gathers up the ashes of the heifer must wash his clothes and be defiled until evening; this is a permanent law for the benefit of the people of Israel and any foreigners living among them.
