Numbers 19:17-19

¹⁷And they shall take of the ashes of the burning, and of the sin (offering), that is, of the cow offered for sin, and they shall put quick waters into a vessel, upon those ashes; (And they shall take some of the ashes from the burning of that sin offering, that is, some of the ashes of the cow offered for sin, and they shall put those ashes into a vessel with fresh water;)

¹⁸in which when a clean man hath dipped hyssop, he shall sprinkle therewith the tent, and all the purtenance of the household, and the men also defouled with such defouling (or and also anyone defiled with such defilement).

¹⁹And in this manner a clean man shall cleanse an unclean thing, in the third (day) and in the seventh day; and he shall be cleansed in the seventh day. And he shall wash himself, and his clothes, and he shall be unclean till to eventide. (And in this manner a clean man shall sprinkle an unclean thing on the third day, and on the seventh day; and it shall be clean on the seventh day. And then he shall wash himself, and his clothes, but he shall be unclean until the evening.)
