Numbers 19:18

And a clean person shall take hyssop, and dip it in the water,
&c.] Three stalks of hyssop bound together, as the Targum of Jonathan, and this man was to be a clean priest, according to the same; but it does not seem necessary that he should be a priest, but that anyone free from ceremonial pollution might do it:

and sprinkle it upon the tent;
where there was a dead body: but this, we are told, is to be understood not of a tent made of wood, or stone, or clay, but made of anything woven, as linen: or of skins ^F21:

and upon all the vessels;
in such a tent, that is, open ones, as before observed:

and upon the persons that were there:
when the man died in it, or came into it since, and while the dead body was in it;

and upon him that touched a bone;
of a dead man, or, as the Targum of Jonathan, the bone of a living man that is separated from him:

or one slain, or one dead;
slain with a sword, or dead of the pestilence, as the same Targum, or of any other disease, or in any other way:

or a grave;
or the covering or side of one, as the same Targum adds.
