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, some render the words, "purify yourselves" (d), "together with the raiment", &c. 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, &c. 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 (e) includes vessels made of the horns, hoofs, and bones of these creatures: and all things made of wood; as beds, cups, dishes, &c. all which might be purified by washing; see Leviticus 15:12.

(d) "purgatote vos", Junius & Tremellius, Piscator; Vid. L'Empereur, Not. ad Kimchii p. 130. (e) Maimon. & Bartenora in Misn. Celim, c. 2. sect. 1.

And purify all your raiment, and all that is made of skins, and all work of goats' hair, and all things made of wood.

31:20 Your raiment - Namely, your spoil and prey. All work - All which had contracted some ceremonial uncleanness either from the dead bodies which wore them, or the tents or houses where they were, in which such dead bodies lay, or from the touch of the Israelitish soldiers, who were legally defiled by the slaughters they made.

that...: Heb. instrument, or, vessel of skins

31:19-24 The Israelites had to purify themselves according to the law, and to abide without the camp seven days, though they had not contracted any moral guilt, the war being just and lawful, and commanded by God. Thus God would preserve in their minds a dread and detestation of shedding blood. The spoil had been used by Midianites, and being now come into the possession of Israelites, it was fit that it should be purified.
