Deuteronomy 8:4

4. Thy raiment waxed not old upon thee, neither did thy foot swell, these forty years--What a striking miracle was this! No doubt the Israelites might have brought from Egypt more clothes than they wore at their outset; they might also have obtained supplies of various articles of food and raiment in barter with the neighboring tribes for the fleeces and skins of their sheep and goats; and in furnishing them with such opportunities the care of Providence appeared. But the strong and pointed terms which Moses here uses (see also De 29:5) indicate a special or miraculous interposition of their loving Guardian in preserving them amid the wear and tear of their nomadic life in the desert. Thirdly, Moses expatiated on the goodness of the promised land.

Verse 4 Thy raiment waxed not old, etc. - The plain meaning of this much-tortured text appears to me to be this: "God so amply provided for them all the necessaries of life, that they never were obliged to wear tattered garments, nor were their feet injured for lack of shoes or sandals." If they had carvers, engravers, silversmiths, and jewelers among them, as plainly appears from the account we have of the tabernacle and its utensils, is it to be wondered at if they also had habit and sandal makers, etc., etc., as we are certain they had weavers, embroiderers, and such like? And the traffic which we may suppose they carried on with the Moabites, or with travelling hordes of Arabians, doubtless supplied them with the materials; though, as they had abundance of sheep and neat cattle, they must have had much of the materials within themselves. It is generally supposed that God, by a miracle, preserved their clothes from wearing out: but if this sense be admitted, it will require, not one miracle, but a chain of the most successive and astonishing miracles ever wrought, to account for the thing; for as there were not less than 600,000 males born in the wilderness, it would imply, that the clothes of the infant grew up with the increase of his body to manhood, which would require a miracle to be continually wrought on every thread, and on every particle of matter of which that thread was composed. And this is not all; it would imply that the clothes of the parent became miraculously lessened to fit the body of the child, with whose growth they were again to stretch and grow, etc. No such miraculous interference was necessary.
