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 "So you must use the ashes from the burnt offering to make that person clean again. Pour fresh water over the ashes into a jar.

18 A clean person must take a hyssop branch and dip it into the water, and then he must sprinkle it over the tent and all its objects. He must also sprinkle the people who were there, as well as anyone who touched a bone, or the body of someone who was killed, or a dead person, or a grave.

19 The person who is clean must sprinkle this water on the unclean people on the third day and on the seventh day. On the seventh day they will become clean. They must wash their clothes and take a bath, and they will be clean that evening.

20 If any who are unclean do not become clean, they must be cut off from the community. Since they were not sprinkled with the cleansing water, they stay unclean, and they could make the Lord's Holy Tent unclean.

21 This is a lasting rule. Those who sprinkle the cleansing water must also wash their clothes, and anyone who touches the water will be unclean until evening.
