Bilangan 19:9

19:9 “‘Then a man who is ceremonially clean must gather up the ashes of the red heifer and put them in a ceremonially clean place outside the camp. They must be kept ¹  for the community of the Israelites for use in the water of purification ²  – it is a purification for sin. ³ 

Bilangan 19:20

19:20 But the man who is unclean and does not purify himself, that person must be cut off from among the community, because he has polluted the sanctuary of the Lord; the water of purification was not sprinkled on him, so he is unclean.

[19:9]  ¹ tn Heb “it will be.”

[19:9]  ² tn The expression לְמֵי נִדָּה (lÿme niddah) is “for waters of impurity.” The genitive must designate the purpose of the waters – they are for cases of impurity, and so serve for cleansing or purifying, thus “water of purification.” The word “impurity” can also mean “abhorrent” because it refers to so many kinds of impurities. It is also called a purification offering; Milgrom notes that this is fitting because the sacrificial ritual involved transfers impurity from the purified to the purifier (pp. 62-72).

[19:9]  ³ sn The ashes were to be stored somewhere outside the camp to be used in a water portion for cleansing someone who was defiled. This is a ritual that was enacted in the wilderness; it is something of a restoring rite for people alienated from community.
