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 And they shall take for the unclean of the burnt ashes of purification, and they shall pour upon them running water into a vessel.
18 And a clean man shall take hyssop, and dip it into the water, and sprinkle it upon the house, and the furniture, and all the souls that are therein, and upon him that touched the human bone, or the slain man, or the corpse, or the tomb.
19 And the clean man shall sprinkle on the unclean on the third day and on the seventh day, and on the seventh day he shall purify himself; and shall wash his garments, and bathe himself in water, and shall be unclean until evening.
20 And whatever man shall be defiled and shall not purify himself, that soul shall be cut off from the midst of the congregation, because he has defiled the holy things of the Lord, because the water of sprinkling has not been sprinkled upon him; he is unclean.
21 And it shall be to you a perpetual statute; and he that sprinkles the water of sprinkling shall wash his garments; and he that touches the water of sprinkling shall be unclean until evening.
