Numbers 19:10 WEB

⁸  He who burns her shall wash his clothes in water, and bathe his flesh in water, and shall be unclean until the even.

⁹  A man who is clean shall gather up the ashes of the heifer, and lay them up outside of the camp in a clean place; and it shall be kept for the congregation of the children of Israel for a water for impurity: it is a sin-offering.

¹⁰  He who gathers the ashes of the heifer shall wash his clothes, and be unclean until the even: and it shall be to the children of Israel, and to the stranger who lives as a foreigner among them, for a statute forever.

¹¹  He who touches the dead body of any man shall be unclean seven days:

¹²  the same shall purify himself therewith on the third day, and on the seventh day he shall be clean: but if he doesn't purify himself the third day, then the seventh day he shall not be clean.
