Even as the Gentiles come to them, and nourish them, there will not be domination. The attitude of the future more powerful kingdoms will not be to conquer, but to establish and nourish. Indeed, thus has been the modern history of Israel and the world powers that established the country.
At the end of this promise, and the restorative picture of respect in the eyes of the nations, the Lord reminds Israel that this is the reward of those who endure to the end - "for they shall not be ashamed that wait for me." The Lord's benefits come in his own time, not ours.
