John Gill Bible Commentary

And your eyes shall see,.... The destruction of the Edomites, and their fruitless attempts to rebuild their desolate places; and the difference between them and the Israelites, who were returned to their own land, and inherited it, when they could not; and the love of God to the one, and his hatred of the other: and ye shall say, The Lord will be magnified from the border of Israel; Aben Ezra interprets it, ye that dwelt in the border of Israel shall say, the Lord shall be magnified, or let him be magnified; let greatness and glory be ascribed to him for what he has done: or, as Kimchi, give him praise and greatness because you are dwelling in your border, and their border is desolate; and your border is called the border of Israel, but theirs the border of wickedness; and so the Targum, "let the glory of the Lord be multiplied, because he hath enlarged the border of Israel;'' and, according to Jarchi, the sense is, he shall show his greatness from our border, to make it known that we are his people: all show and own that God had loved them more than others, and therefore they ought to have honoured and obeyed him, in which they were deficient, and so ungrateful.
