Thy shoes shall be iron and brass,.... Either they should have such an abundance of these metals, that they could if they would have made their shoes of them; but that is not usual; though it is said of Empedocles (g) the philosopher, that he wore shoes of brass, which was very singular; and some think that this tribe, because of the abundance of these metals, used to stick their shoes with iron and brass nails at the bottom of them, as country people, soldiers, and travellers in various nations do; but the true sense seems to be, that the land that fell to this tribe, and on which they trod, should yield much iron and brass; as in Carmel, a mountain on the borders of it, brass was taken, as says Hesychius; and Zidon is by Homer (i) said to abound with brass, which belonged to this tribe; and Sarepta, another city in it, had its name from which signifies to melt, from the melting of these metals in it; see Deu 8:9; though some Jewish writers take the sense to be, that the land of Asher was so strongly fortified as if it had been enclosed with walls of brass and iron, or the gates of its cities were shut up with bolts and bars of iron and brass, as Jarchi, Kimchi, and Ben Melech observe; so the Arabic: and as thy days, so shall thy strength be; the same in old age as in youth; which is the sense of the Latin Vulgate version, and all the Targums: such were the vigour and strength of. Moses himself, Deu 34:7; and so may denote a renewal of youth, like that of eagles; and, in a spiritual sense, a revival of the graces of the Spirit of God, as to the exercise of them, and an increase of spiritual strength, so that the inward man is renewed day by day; and may also denote such a measure of strength given, as is proportioned to the events that daily befall, or to the services and sufferings men are called unto; see Co1 10:13.
