(9) In that day shall his strong cities be as a forsaken bough.--Better, his fortified cities shall be like a forsaken tract of forest and hill-top. These were naturally the usual sites of fortresses (2Chronicles 27:4), and the gist of the prediction is that they shall be left uninhabited and in ruins. The LXX., it may be noticed, either followed a different reading or else give a curious paraphrase, "thy cities shall be forsaken, like as the Amorites and Hivites forsook them before the face of the children of Israel." The whole verse reminds us of the "great forsaking" of Isaiah 6:12.

Verse 9. - In that day. While a remnant of the Israelites shall repent and turn to God, throwing in their lot with Judah, as it would seem the country generally shall feel the weight of God's chastening hand, on account of Israel's former sins and offences. As a forsaken bough, and an uppermost branch; rather, as the forsaken tract of woodland and mountain-crest (Kay). The reference is to the condition of the land when it passed out of the possession of the Canaanitish nations. It was then forsaken and desolate. So shall it be once more, when Israel is expelled for the same sins (see 2 Kings 17:7, 8). Which they left because of the children of Israel; rather, which men forsook before the children of Israel; i.e. from which the Canaanites fled as the children of Israel advanced and took possession. The writer ignores the long and fierce struggle which the Canaanites made, and looks only to the result - retirement from a desolated country.

17:1-11 Sin desolates cities. It is strange that great conquerors should take pride in being enemies to mankind; but it is better that flocks should lie down there, than that they should harbour any in open rebellion against God and holiness. The strong holds of Israel, the kingdom of the ten tribes, will be brought to ruin. Those who are partakers in sin, are justly made partakers in ruin. The people had, by sins, made themselves ripe for ruin; and their glory was as quickly cut down and taken away by the enemy, as the corn is out of the field by the husbandman. Mercy is reserved in the midst of judgment, for a remnant. But very few shall be marked to be saved. Only here and there one was left behind. But they shall be a remnant made holy. The few that are saved were awakened to return to God. They shall acknowledge his hand in all events; they shall give him the glory due to his name. To bring us to this, is the design of his providence, as he is our Maker; and the work of his grace, as he is the Holy One of Israel. They shall look off from their idols, the creatures of their own fancy. We have reason to account those afflictions happy, which part between us and our sins. The God of our salvation is the Rock of our strength; and our forgetfulness and unmindfulness of him are at the bottom of all sin. The pleasant plants, and shoots from a foreign soil, are expressions for strange and idolatrous worship, and the vile practices connected therewith. Diligence would be used to promote the growth of these strange slips, but all in vain. See the evil and danger of sin, and its certain consequences.In that day shall his strong cities be as a forsaken bough, and an uppermost branch,.... Meaning the strong cities of Ephraim or Jacob, the ten tribes, which should be forsaken of their inhabitants; having fled from before the enemy, or being slain or carried captive; like a bough of a tree, that is forsaken stripped of its leaves, and an uppermost branch of a tree that is dead and dry, and has nothing on it:

which they left; or "as they left", or "were left":

because of the children of Israel; "from the face of" them; or for fear of them; that is, the same cities which the Canaanites left; and as they left them, or were left by them, for fear of the Israelites; the same, and in the same manner, shall they be left by the Israelites, for fear of the Assyrians; and so the Septuagint version reads the words,

"in that day thy cities shall be forsaken, in like manner as the Amorites and Hivites left them, from the face of the children of Israel;''

and this sense is given by Aben Ezra and Kimchi: though some interpret it of some places being spared and left for the remnant to dwell in; but what follows in this verse, and in the next Isaiah 17:10, shows the contrary sense:

and there shall be desolation; over all those cities, and in all the land; though Aben Ezra particularly applies it to Samaria, the royal city. Jerom interprets the whole of the cities of Judea being forsaken of their inhabitants, when the Romans besieged Jerusalem, and made the land desolate; which calamity came upon them, for their neglect and forgetfulness of Jesus the Saviour.
