Numbers 19:9; Numbers 19:10; Numbers 19:17

9 “A man who is clean shall gather up the ashes of the heifer and put them in a ceremonially clean place outside the camp. They are to be kept by the Israelite community for use in the water of cleansing; it is for purification from sin.

10 The man who gathers up the ashes of the heifer must also wash his clothes, and he too will be unclean till evening. This will be a lasting ordinance both for the Israelites and for the foreigners residing among them.

17 “For the unclean person, put some ashes from the burned purification offering into a jar and pour fresh water over them.
