Ashes kept for the congregation

9Then a clean man shall gather the ashes of the heifer and place them outside the camp in a clean place, and they shall be kept for the congregation of the sons of Israel for water for impurity; it is a sin offering.

10And the one who gathers the ashes of the heifer shall wash his clothes, and he shall be unclean until the evening. And this shall be for the sons of Israel and for the sojourner who sojourns among them as a permanent statute.
