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 "Here is what I want you to do for someone who is not 'clean.' Put some ashes from the burned young cow into a jar. Pour fresh water on the ashes.

18 Then a man who is 'clean' must dip branches of a hyssop plant in the water. He must sprinkle the tent with it. Everything that belongs to the tent must be sprinkled with it. The people who were in the tent must also be sprinkled. Anyone who has touched a human bone or a grave must be sprinkled. So must anyone who has touched someone who has been killed. So must anyone who has touched someone who has died a natural death.

19 "The man who is 'clean' must sprinkle the person who is not. That must be done on the third and seventh days. On the seventh day the person who is not 'clean' must be made pure and clean. The one who is being made 'clean' must wash his clothes. He must take a bath. Then that evening he will be 'clean.'

20 "But what if a person who is 'unclean' does not make himself pure and clean? Then he must be cut off from the community. He has made my holy tent 'unclean.' The special water has not been sprinkled on him. He is not 'clean.'

21 That law will apply to all of those people for all time to come. "The man who sprinkles the special water must also wash his clothes. Anyone who touches the water will be 'unclean' until evening.
