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 To remove the uncleanness, some ashes from the red cow which was burned to remove sin shall be taken and put in a pot, and fresh water added.
18 In the first case, someone who is ritually clean is to take a sprig of hyssop, dip it in the water, and sprinkle the tent, everything in it, and the people who were there. In the second case, someone who is ritually clean is to sprinkle the water on those who had touched the human bone or the dead body or the grave.
19 On the third day and on the seventh the person who is ritually clean is to sprinkle the water on the unclean persons. On the seventh day he is to purify those, who, after washing their clothes and pouring water over themselves, become ritually clean at sunset.
20 Those who have become ritually unclean and do not purify themselves remain unclean, because the water for purification has not been thrown over them. They defile the Lord's Tent and will no longer be considered God's people.
21 You are to observe this rule for all time to come. The person who sprinkles the water for purification must also wash his clothes; anyone who touches the water remains ritually unclean until evening.
