Those who put contempt and reproach on God's people, will have them turned on themselves. God promises favour to his Israel. We have no reason to complain, if the more unkind men are, the more kind God is.
They shall come again to their own border. It was a type of the heavenly Canaan, of which all God's children are heirs, and into which they all shall be brought together. And when God returns in mercy to a people who return to him in duty, all their grievances will be set right.
The full completion of this prophecy must be in some future event.
