Numbers 19:17-19

Revised Standard Version

¹⁷ For the unclean they shall take some ashes of the burnt sin offering, and running water shall be added in a vessel; ¹⁸ then a clean person shall take hyssop, and dip it in the water, and sprinkle it upon the tent, and upon all the furnishings, and upon the persons who were there, and upon him who touched the bone, or the slain, or the dead, or the grave; ¹⁹ and the clean person shall sprinkle upon the unclean on the third day and on the seventh day; thus on the seventh day he shall cleanse him, and he shall wash his clothes and bathe himself in water, and at evening he shall be clean.
