How the ten tribes deserted the house of David we read in the foregoing chapter. They had formerly sat loose to that family (Sa2 20:1, Sa2 20:2), and now they quite threw it off, not considering how much it would weaken the common interest and take Israel down from that pitch of glory at which it had arrived in the last reign. But thus the kingdom must be corrected as well as the house of David. 1. Rehoboam at length, like a bold man, raises an army, with a design to reduce the revolters, Ch2 11:1. Judah and Benjamin were not only resolved to continue their allegiance to him, but ready to give him the best assistance they could for the recovery of his right. Judah was his own tribe, that owned him some years before the rest did; Benjamin was the tribe in which Jerusalem, or the greatest part of it, stood, which perhaps was one reason why that tribe clave to him. 2. Yet, like a conscientious man, when God forbade him to prosecute this design, in obedience to him he let it fall, either because he reverenced the divine authority or because he knew that he should not prosper if he should go contrary to God's command, but instead of retrieving what was lost would be in danger of losing what he had. It is dangerous undertaking any thing, but especially undertaking a war, contrary to the will of God. God calls him (Ch2 11:3), Rehoboam the son of Solomon, to intimate that this was determined for the sin of Solomon, and it would be to no purpose to oppose a decree that had gone forth. They obeyed the words of the Lord; and though it looked mean, and would turn to their reproach among their neighbours, yet, because God would have it so, they laid down their arms. 3. Like a discreet man, he fortified his own country. He saw it was to no purpose to think of reducing those that had revolted. A few good words might have prevented their defection, but now all the forces of his kingdom cannot bring them back. The think is done, and so it must rest; it is his wisdom to make the best of it. Perhaps the same young counsellors that had advised him to answer them roughly urged him to fight them, notwithstanding the divine inhibition; but he had paid dearly enough for being advised by them, and therefore now, we may suppose, his aged and experienced counsellors were hearkened to, and they advised him to submit to the will of God concerning what was lost, and to make it his business to keep what he had. It was probably by their advice that, (1.) He fortified his frontiers, and many of the principal cities of his kingdom, which, in Solomon's peaceable reign, no care had been taken for the defence of. (2.) He furnished them with good stores of victuals and arms, Ch2 11:11, Ch2 11:12. Because God forbade him to fight, he did not therefore sit down sullenly, and say that he would do nothing for the public safety if he might not do that, but prudently provided against an attack. Those that may not be conquerors, yet may be builders.

And built cities for defense in Judah - He was obliged to strengthen his frontiers against the encroachments of the men of Israel; and Jeroboam did the same thing on his part to prevent the inroads of Judah. See Kg1 12:25.

And Adoraim,.... Called by Josephus (d) Adora, which he mentions along with Mareshah, or Marissa:

and Lachish: a royal city in the time of the Canaanites, and which fell to the lot of Judah, Jos 12:11,

and Azekah; a city situated in the plain of Judah, Jos 10:10.

built cities for defence in Judah--This is evidently used as the name of the southern kingdom. Rehoboam, having now a bitter enemy in Israel, deemed it prudent to lose no time in fortifying several cities that lay along the frontier of his kingdom. Jeroboam, on his side, took a similar precaution (Kg1 12:25). Of the fifteen cities named, Aijalon, now Yalo, and Zorah, now Surah, between Jerusalem and Jabneh [ROBINSON], lay within the province of Benjamin. Gath, though a Philistine city, had been subject to Solomon. And Etham, which was on the border of Simeon, now incorporated with the kingdom of Israel, was fortified to repel danger from that quarter. These fortresses Rehoboam placed under able commanders and stocked them with provisions and military stores, sufficient, if necessary, to stand a siege. In the crippled state of his kingdom, he seems to have been afraid lest it might be made the prey of some powerful neighbors.
