Numbers 19:19 Meaning and Commentary

Numbers 19:19

And the clean person shall sprinkle upon the unclean
The clean priest shall sprinkle upon the unclean man, as the Targum of Jonathan; that is, he shall sprinkle the water of purification upon him that is unclean in any of the above ways:

on the third day, and on the seventh day; (See Gill on Numbers 19:12),

and on the seventh day he shall purify himself;
either the unclean person, who shall perfect his purification, as Jarchi interprets it, that is, by doing what follows; or else the clean person, who becomes in some measure unclean, by sprinkling and touching the water of separation, as appears from ( Numbers 19:21 ) as the priest that sprinkled the blood of the heifer, and the man that burnt it and gathered its ashes, ( Numbers 19:7-9 )

and wash his clothes, and bathe himself in water, and shall be clean at
even;
in like manner as the man that let go the goat into the wilderness, ( Leviticus 16:26 ) .

Numbers 19:19 In-Context

17 For the unclean they shall take some ashes of the burnt purification offering, and running water shall be added in a vessel;

18 then a clean person shall take hyssop, dip it in the water, and sprinkle it on the tent, on all the furnishings, on the persons who were there, and on whoever touched the bone, the slain, the corpse, or the grave.

19 The clean person shall sprinkle the unclean ones on the third day and on the seventh day, thus purifying them on the seventh day. Then they shall wash their clothes and bathe themselves in water, and at evening they shall be clean.

20 Any who are unclean but do not purify themselves, those persons shall be cut off from the assembly, for they have defiled the sanctuary of the Lord. Since the water for cleansing has not been dashed on them, they are unclean.

21 It shall be a perpetual statute for them. The one who sprinkles the water for cleansing shall wash his clothes, and whoever touches the water for cleansing shall be unclean until evening.
