Parallel
Numbers 19:9
Brenton's English Septuagint · Berean Standard Bible
And a clean man shall gather up the ashes of the heifer, and lay them up in a clean place outside the camp; and they shall be for the congregation of the children of Israel to keep: it is the water of sprinkling, a purification.
Then a man who is ceremonially clean is to gather up the ashes of the heifer and store them in a ceremonially clean place outside the camp. They must be kept by the congregation of Israel for preparing the water of purification; this is for purification from sin.
