Numbers 19:17-20

¹⁷and they have taken for the unclean person of the ashes of the burning of the cleansing, and he hath put upon it running water unto a vessel;

¹⁸and a clean person hath taken hyssop, and hath dipped it in water, and hath sprinkled on the tent, and on all the vessels, and on the persons who have been there, and on him who is coming against a bone, or against one pierced, or against the dead, or against a grave.

¹⁹'And the clean hath sprinkled it on the unclean on the third day, and on the seventh day, and hath cleansed him on the seventh day, and he hath washed his garments, and hath bathed with water, and hath been clean in the evening.

²⁰'And the man who is unclean, and doth not cleanse himself, even that person hath been cut off from the midst of the assembly; for the sanctuary of Jehovah he hath defiled; water of separation is not sprinkled upon him; he is unclean.
