We have here the breaking out of Absalom's rebellion, which he had long been contriving. It is said to be after forty years, Sa2 15:7. But whence it is to be dated we are not told; not from David's beginning his reign, for then it would fall in the last year of his life, which is not probable; but either from his first anointing by Samuel seven years before, or rather (I think) from the people's desiring a king, and the first change of the government into a monarchy, which might be about ten years before David began to reign; it is fitly dated thence, to show that the same restless spirit was still working, and still they were given to change: as fond now of a new man as then of a new model. So it fell about the thirtieth year of David's reign. Absalom's plot being now ripe for execution,

I.The place he chose for the rendezvous of his party was Hebron, the place where he was born and where his father began his reign and continued it several years, which would give some advantage to his pretensions. Every one knew Hebron to be a royal city; and it lay in the heart of Judah's lot, in which tribe, probably, he thought his interest strong.

II.The pretence he had both to go thither and to invite his friends to him there was to offer a sacrifice to God, in performance of a vow he had made during his banishment, Sa2 15:7, Sa2 15:8. We have cause enough to suspect that he had not made any such vow; it does not appear that he was so religiously inclined. But he that stuck not at murder and treason would not make conscience of a lie to serve his purpose. If he said he had made such a vow, nobody could disprove him. Under this pretence, 1. He got leave of his father to go to Hebron. David would be well pleased to hear that his son, in his exile, was so desirous to return to Jerusalem, not only his father's city, but the city of the living God, - that he looked up to God, to bring him back, - that he had vowed, if he were brought back, to serve the Lord, whose service he had hitherto neglected, - and that now, being brought back, he remembered his vow, and resolved to perform it. If he think fit to do it in Hebron, rather than in Sion or Gibeon, the good king is so well pleased with the thing itself that he will not object against his choice of the place. See how willing tender parents are to believe the best concerning their children, and, upon the least indication of good, to hope, even concerning those that have been untoward, that they will repent and reform. But how easy is it for children to take advantage of their good parents' credulity, and to impose upon them with the show of religion, while still they are what they were! David was overjoyed to hear that Absalom inclined to serve the Lord, and therefore readily gave him leave to go to Hebron, and to go thither with solemnity. 2. He got a good number of sober substantial citizens to go along with him, Sa2 15:11. There went 200 men, probably of the principal men of Jerusalem, whom he invited to join with him in his feast upon his sacrifice; and they went in their simplicity, not in the least suspecting that Absalom had any bad design in this journey. He knew that it was to no purpose to tempt them into his plot: they were inviolably firm to David. But he drew them in to accompany him, that the common people might think that they were in his interest, and that David was deserted by some of his best friends. Note, It is no new thing for very good men, and very good things, to be made use of by designing men to put a colour upon bad practices. When religion is made a stalking-horse, and sacrifice a shoeing-horn, to sedition and usurpation it is not to be wondered at if some that were well affected to religion, as these followers of Absalom here, are imposed upon by the fallacy, and drawn in to give countenance to that, with their names, which in their heart they abhor, not having known the depths of Satan.

III.The project he laid was to get himself proclaimed king throughout all the tribes of Israel upon a signal given, Sa2 15:10. Spies were sent abroad, to be ready in every country to receive the notice with satisfaction and acclamations of joy, and to make the people believe that the news was both very true and very good, and that they were all concerned to take up arms for their new king. Upon the sudden spreading of this proclamation, "Absalom reigns in Hebron," some would conclude that David was dead, others that he had resigned: and thus those that were in the secret would draw in many to appear for Absalom, and to come into his assistance, who, if they had rightly understood the matter, would have abhorred the thought of it, but, being drawn in, would adhere to him. See what artifices ambitious men use for the compassing of their ends; and in matters of state, as well as in matters of religion, let us not be forward to believe every spirit, but try the spirits.

IV.The person he especially courted and relied upon in this affair was Ahithophel, a politic thinking man, and one that had a clear head and a great compass of thought, that had been David's counsellor, his guide and his acquaintance (Psa 55:13), his familiar friend, in whom he trusted, who did eat of his bread, Psa 41:9. But, upon some disgust of David's against him, or his against David, he was banished, or retired from public business, and lived privately in the country. How should a man of such good principles as David, and a man of such corrupt principles as Ahithophel, long agree? A fitter tool Absalom could not find in all the kingdom than one that was so great a statesman, and yet was disaffected to the present ministry. While Absalom was offering his sacrifices, in performance of his pretended vow, he sent for this man. So much was his heart on the projects of his ambition that he could not stay to make an end of his devotion, which showed what his eye was upon in all, and that it was but for a pretence that he made long offerings.

V.The party that joined with him proved at last very considerable. The people increased continually with Absalom, which made the conspiracy strong and formidable. Every one whom he had complimented and caressed (pronouncing his matters right and good, especially if afterwards the cause went against him) not only came himself, but made all the interest he could for him, so that he wanted not for numbers. The majority is no certain rule to judge of equity by. All the world wondered after the beast. Whether Absalom formed this design merely in the height of his ambition and fondness to rule, or whether there was not in it also malice against his father and revenge for his banishment and confinement, though this punishment was so much less than he deserved, does not appear. But, generally, that which aims at the crown aims at the head that wears it.

While I abode at Geshur in Syria - Geshur, the country of Talmai, was certainly not in Syria, but lay on the south of Canaan, in or near Edom, as is evident from Jdg 1:10; Sa1 27:8; Sa2 13:37. Hence it is probable that ארם Aram, Syria, is a mistake for אדם Edom; ד daleth and ר resh being easily interchangeable. Edom is the reading both of the Syriac and Arabic.

I will serve the Lord - Here he pretended to be a strict follower of Jehovah, even while he was in a heathen country; and now he desires liberty to go and perform a vow at Hebron, which he pretends to have made while he was resident at Geshur. And all this was the more perfectly to organize his system of rebellion against his venerable father.

For thy servant vowed a vow while I abode at Geshur in Syria,.... When at his grandfather's court there:

saying, if the Lord will bring me again indeed to Jerusalem; which he might be sincerely desirous of:

then I will serve the Lord; but it is a question whether he ever made a vow to this purpose, or concerned himself about serving the Lord; but it rather may be, this was a lie of his, now framed in order to get leave of the king to go to Hebron.

after forty years--It is generally admitted that an error has here crept into the text, and that instead of "forty," we should read with the Syriac and Arabic versions, and JOSEPHUS, "four years"--that is, after Absalom's return to Jerusalem, and his beginning to practice the base arts of gaining popularity.

my vow, which I have vowed unto the Lord--during his exile in Geshur. The purport of it was, that whenever God's providence should pave the way for his re-establishment in Jerusalem, he would offer a sacrifice of thanksgiving. Hebron was the spot selected for the performance of this vow, ostensibly as being his native place (Sa2 3:3), and a famous high place, where sacrifices were frequently offered before the temple was built; but really as being in many respects the most suitable for the commencement of his rebellious enterprise. David, who always encouraged piety and desired to see religious engagements punctually performed, gave his consent and his blessing.
