(4.) He must give them a prospect of the destruction of these enemies, at last, that were now such a terror to them. [1.] They should neither of them enlarge their dominions, nor push their conquests any further; The head city of Syria is Damascus, and the head man of Damascus is Rezin; this he glories in, and this let him be content with, v. 8. The head city of Ephraim has long been Samaria, and the head man in Samaria is now Pekah the son of Remaliah. These shall be made to know their own, their bounds are fixed, and they shall not pass them, to make themselves masters of the cities of Judah, much less to make Jerusalem their prey. Note, As God has appointed men the bounds of their habitation (Acts xvii. 26), so he has appointed princes the bounds of their dominion, within which they ought to confine themselves, and not encroach upon their neighbours' rights. [2.] Ephraim, which perhaps was the more malicious and forward enemy of the two, should shortly be quite rooted out, and should be so far from seizing other people's lands that they should not be able to hold their own. Interpreters are much at a loss how to compute the sixty-five years within which Ephraim shall cease to be a people; for the captivity of the ten tribes was but eleven years after this: and some make it a mistake of the transcriber, and think it should be read within six and five years, just eleven. But it is hard to allow that. Others make it to be sixty-five years from the time that the prophet Amos first foretold the ruin of the kingdom of the ten tribes; and some late interpreters make it to look as far forward as the last desolation of that country by Esarhaddon, which was about sixty-five years after this; then Ephraim was so broken that it was no more a people. Now it was the greatest folly in the world for those to be ruining their neighbours who were themselves marked for ruin, and so near to it. See what a prophet told them at this time, when they were triumphing over Judah, 2 Chron. xxviii. 10. Are there not with you, even with you, sins against the Lord your God?
