Thy raiment waxed not old upon thee, &c] They wanted not clothes all the forty years they were in the wilderness; which some account for by the rising generation being supplied with the clothes of those that died in the wilderness, and with the spoils they took from Amalek, Ex 17:1 and others, as Aben Ezra observes, remark that they brought much clothes with them out of Egypt, which no doubt they did; see Ex 12:35 and he adds, as worthy of notice, that the manna they lived upon did not produce sweat, which is prejudicial to clothes; but be it so, that they were sufficiently provided with clothes, it must be miraculous that these clothes they wore should not wax old.
This, in a spiritual sense, may denote the righteousness of Christ, which is often compared to raiment, the property of which is, that it never waxes old, wears out, or decays; it is an everlasting righteousness, and will never be abolished, but will answer for the saints in a time to come; see Isa 51:6 neither did thy foot swell these forty years; or puff up like paste, as Jarchi explains it, which is often the case in long journeys; the Septuagint version is, "did not become callous"; a callousness or hardness is frequently produced by travelling; in De 29:5 it is explained of the shoes on their feet not waxing old; so Ben Melech, and the Targums of Onkelos and Jonathan, and the Syriac and Arabic versions here, "thy feet were not naked", were not without shoes; these were no more wore out by travel than their clothes upon their backs, and this was equally as miraculous: the Gibeonites, pretending to come from a far country, and to have travelled much and long, put on old garments and old shoes, to make it probable and plausible, Jos 9:5.
