(9) So do God to Abner.--The anger of Abner culminates in a solemn oath to transfer the kingdom to David, "as the Lord hath sworn to him." There is no record of a Divine oath to give the kingdom to David, but the prophetic declaration that God's choice of him was unalterable (1Samuel 15:29) may well have been considered to have the force of an oath. Abner does not propose to do this in order to fulfil the Divine will, for his words show that he had been acting hitherto in conscious opposition to that will, but to revenge himself for the insult now offered him. He had doubtless also become satisfied of his master's entire unfitness for the throne, and his power over Israel opened before him the prospect of high preferment from David.

Verse 9. - As the Lord hath sworn to David. This not only shows that the prophetic promise of the kingdom to David was generally known (see note on 2 Samuel 1:2), but that Abner regarded it as solemnly ratified. There is no express mention of any such oath, but Abner was a man of strong words, and possibly only meant that Jehovah's purpose was becoming evident by the course of events.

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.So do God to Abner, and more also,.... He wishes the worst of evils to himself, such as he cared not to name; but left them to be supposed what he meant as utter ruin and destruction of himself, soul and body:

except as the Lord hath sworn to David, even so I do to him; meaning if he did not do that David, which God had sworn should be done, namely, what follows, the translation of the kingdom to him; by which it appears that Abner knew of the promise and oath of God respecting this matter; and therefore acted against his conscience, in setting up Ishbosheth on the throne; which he knew would not prosper, and that he was fighting against God; which shows what a hardened wicked creature he was, and how far ambition, and being thought to be of consequence, will carry a man.
