2 Samuel 3:21-22. Abner said, I will gather all Israel unto my lord the king — How empty and ill founded are the purposes of vain man! Abner, who here promises kingdoms, soon found that he could not ensure to himself one hour of life. David had sent him away, and he departed in peace; but, Behold, the servants of David and Joab came from pursuing a troop — In those times of distraction between Judah and Israel, we may well think their neighbours, who were enemies to both, namely, the Philistines, Edomites, Moabites, and others, made many inroads upon the country to get spoil. Joab, however, and the valiant men about David, watched to prevent this, and at this time had overtaken a company of them, in their return home, and recovered a great booty from them.

3:7-21 Many, like Abner, are not above committing base crimes, who are too proud to bear reproof, or even the suspicion of being guilty. While men go on in sin, and apparently without concern, they are often conscious that they are fighting against God. Many mean to serve their own purposes; and will betray those who trust them, when they can get any advantage. Yet the Lord serves his own designs, even by those who are thus actuated by revenge, ambition, or lust; but as they intend not to honour him, in the end they will be thrown aside with contempt. There was real generosity both to Michal and to the memory of Saul, in David's receiving the former, remembering probably how once he owed his life to her affection, and knowing that she was separated from him partly by her father's authority. Let no man set his heart on that which he is not entitled to. If any disagreement has separated husband and wife, as they expect the blessing of God, let them be reconciled, and live together in love.Abner repeats the offer 2 Samuel 3:12; and the condition of Michal's return 2 Samuel 3:13 being now fulfilled, David accepts it, and the league between them was solemnly ratified at David's board, amidst the rites of hospitality. 17-21. Abner had communication with the elders of Israel—He spoke the truth in impressing their minds with the well-known fact of David's divine designation to the kingdom. But he acted a base and hypocritical part in pretending that his present movement was prompted by religious motives, when it sprang entirely from malice and revenge against Ish-bosheth. The particular appeal of the Benjamites was a necessary policy; their tribe enjoyed the honor of giving birth to the royal dynasty of Saul; they would naturally be disinclined to lose that prestige. They were, besides, a determined people, whose contiguity to Judah might render them troublesome and dangerous. The enlistment of their interest, therefore, in the scheme, would smooth the way for the adhesion of the other tribes; and Abner enjoyed the most convenient opportunity of using his great influence in gaining over that tribe while escorting Michal to David with a suitable equipage. The mission enabled him to cover his treacherous designs against his master—to draw the attention of the elders and people to David as uniting in himself the double recommendation of being the nominee of Jehovah, no less than a connection of the royal house of Saul, and, without suspicion of any dishonorable motives, to advocate policy of terminating the civil discord, by bestowing the sovereignty on the husband of Michal. In the same character of public ambassador, he was received and feted by David; and while, ostensibly, the restoration of Michal was the sole object of his visit, he busily employed himself in making private overtures to David for bringing over to his cause those tribes which he had artfully seduced. Abner pursued a course unworthy of an honorable man and though his offer was accepted by David, the guilt and infamy of the transaction were exclusively his. All Israel, i.e. the elders and chieftains of all Israel, representing and ruling all the rest.

And Abner said to David, I will arise and go,.... Into the several parts of the land of Israel:

and will gather all Israel unto my lord the king; the princes of the several tribes, and the elders of the people, their heads and principal men:

that they may make a league with thee; come into the league and covenant now made with Abner, and those with him:

and that thou mayest reign over all that thine heart desireth: which he supposed reached to all the people of the house of Israel and of Judah, though David had not expressed any eager and impatient desire of government, but waited the Lord's time to be put into the possession of the whole kingdom of Israel:

and David sent Abner away, and he went in peace; with inward satisfaction of mind, pleased that things were so well settled and adjusted to the content of all parties, and with outward satiety of body, no insults or attempts being made upon him by any of David's men; which perhaps would not have been the case if Joab had been at court, as may be concluded from what follows.

And Abner said unto David, I will arise and go, and will gather all Israel unto my lord the king, that they may make a league with thee, and that thou mayest reign over all that thine heart desireth. And David sent Abner away; and he went in peace.
