Gill's Exposition of the Entire BibleAnd when Rehoboam was come to Jerusalem,.... After he had been at Shechem, and had given his answer to the request of the men of Israel, upon which they revolted from him: this and the three following verses are the same with 1 Kings 12:21. See Gill on 1 Kings 12:21.
Keil and Delitzsch Biblical Commentary on the Old TestamentRehoboam's attitude to the ten rebel tribes. Cf. 1 Kings 12:21-24. - Rehoboam's purpose, to subdue these tribes by force of arms, and bring them again under his dominion, and the abandonment of this purpose in consequence of the command of the prophet Shemaiah, belong in a certain measure to the history of the revolt of the ten tribes from the house of David; for the revolt only became an accomplished fact when the prophet Shemaiah proclaimed in the name of the Lord that the matter was from the Lord. 2 Chronicles 11:3. Of Jahve was the thing done; He had ordained the revolt as a chastisement of the seed of David for walking no more in His ways. Solomon had, by allowing himself to be seduced by his many foreign wives into departing from the Lord, exposed himself to the divine displeasure, and his successor Rehoboam increased the guilt by his impolitic treatment of the tribes dissatisfied with Solomon's rule, and had, if not brought about the revolt, yet hastened it; but yet the conduct of these tribes was not thereby justified. Their demand that the burdens laid upon them by Solomon should be lightened, flowed from impure and godless motives, and at bottom had its root in discontent with the theocratic rule of the house of David (see on 1 Kings 12:21.). The expression, "to all Israel in Judah and Benjamin," is deeper than "the whole house of Judah and Benjamin and the remnant of the people," i.e., those belonging to the other tribes who were dwelling in the tribal domains of Judah and Benjamin (1 Kings 12:23); for it characterizes all who had remained true to the house of David as Israel, i.e., those who walked in the footsteps of their progenitor Israel (Jacob).
Geneva Study BibleAnd when Rehoboam was come to Jerusalem, he gathered of the house of Judah and {a} Benjamin an hundred and fourscore thousand chosen men, which were warriors, to fight against {b} Israel, that he might bring the kingdom again to Rehoboam. (a) That is, the half tribe of Benjamin for the other half went after Jeroboam. (b) Meaning the ten tribes who rebelled.

Matthew Henry's Concise Commentary11:1-12 A few good words might have prevented the rebellion of Rehoboam's subjects; but all the force of his kingdom cannot bring them back. And it is in vain to contend with the purpose of God, when it is made known to us. Even those who are destitute of true faith, will at times pay some regard to the word of God, and be kept by it from wrong actions, to which they are prone by nature.
Matthew Henry's Whole Bible CommentaryChapter 11 We are here going on with the history of Rehoboam. I. His attempt to recover the ten tribes he has lost, and the letting fall of that attempt in obedience to the divine command (v. 1-4). II. His successful endeavours to preserve the two tribes that remained (v. 5-12). III. The resort of the priests and Levites to him (v. 13-17). IV. An account of his wives and children (v. 18-23). Verses 1-12 How the ten tribes deserted the house of David we read in the foregoing chapter. They had formerly sat loose to that family (2 Sa. 20:1, 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, v. 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 (v. 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, v. 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. |
