God does not only promise mercy here to the Jews, but also to heathen nations, of whom he would be the Judge, to punish them for the sake of his people. And that this passage is to be extended to aliens is evident from the context; for the Prophet immediately adds, "And it shall be, that when they shall learn the ways of my people, to swear in my name, Live does Jehovah, as they have taught my people to swear by Baal, then shall they be built in the midst of my people." We hence see that God would not only shew mercy to the remnant of his elect people, but also to their enemies.

If it be objected, -- that thus God's favor, manifested towards the children of Abraham, was obscured, the answer is, -- that this availed much to confirm the hope of the faithful; for they had not only to look for their own salvation, but also for that of their enemies, whom God would gather together with them. Thus God rendered double his favor to the Israelites. The Prophet also in this place confirms in a striking manner the confidence of the faithful; for he says that God would be merciful even to their enemies for their sake, as they would be saved in common with themselves. We now then understand the object of the Prophet, when he declares, that God, after having drawn out the Gentiles from their own countries, would again be merciful to them, so as to restore every one of them to their own inheritance and to their own place.
