Numbers 31:20

And purify all your raiment
By washing them; and this may intend not so much their own wearing apparel, as the raiment they took off of the dead bodies of the Midianites, since the person that touched a dead body was not obliged to wash his clothes, but the clean person that sprinkled the water of purification on him, ( Numbers 19:19 Numbers 19:21 ) , some render the words, "purify yourselves" ^F4, "together with the raiment" which seems to be the best version of them:

and all that is made of skins;
of any sort of creatures, as the covering of tents, shoes, bottles see ( Leviticus 11:32 )

and all work of goats' hair;
such as the covering of tents was also made of: and this, according to Jarchi and other Jewish writers ^F5 includes vessels made of the horns, hoofs, and bones of these creatures: and all things made of wood; as beds, cups, dishes all which might be purified by washing; see ( Leviticus 15:12 ) .
