And a man [that is] clean shall gather up the ashes of the heifer, and lay [them] up without the camp in a clean place, and it shall be kept for the congregation of the children of Israel for a (e) water of separation: it [is] a purification for sin.
(e) Or, the water of separation because they that were separate due to their uncleanness, were sprinkled with it and made clean, (Numbers 8:7). It is also called holy water, because it was ordained for a holy use, (Numbers 1:17).
