And it shall come to pass, when the Lord shall have done to my lord according to all the good that he hath spoken concerning thee,.... Performed his promise, especially with respect to his kingdom, as follows:

and shall have appointed thee ruler over Israel; that is, actually raised him to be, and settled him as king upon the throne of Israel; for he was both appointed and anointed already; and this Abigail knew, and was now well known in Israel, and the common talk of the people.

Abigail concluded her intercession with the assurance that the forgiveness of Nabal's act would be no occasion of anguish of heart to David when he should have become prince over Israel, on account of his having shed innocent blood and helped himself, and also with the hope that he would remember her. From the words, "When Jehovah shall do to my lord according to all the good that He hath spoken concerning him, and shall make thee prince over Israel," it appears to follow that Abigail had received certain information of the anointing of David, and his designation to be the future king, probably through Samuel, or one of the pupils of the prophets. There is nothing to preclude this assumption, even if it cannot be historically sustained. Abigail manifests such an advance and maturity in the life of faith, as could only have been derived from intercourse with prophets. It is expressly stated with regard to Elijah and Elisha, that at certain times the pious assembled together around the prophets. What prevents us from assuming the same with regard to Samuel? The absence of any distinct testimony to that effect is amply compensated for by the brief, and for the most part casual, notices that are given of the influence which Samuel exerted upon all Israel.

And it shall come to pass, when the LORD shall have done to my lord according to all the good that he hath spoken concerning thee, and shall have appointed thee ruler over Israel;

25:18-31 By a present Abigail atoned for Nabal's denial of David's request. Her behaviour was very submissive. Yielding pacifies great offences. She puts herself in the place of a penitent, and of a petitioner. She could not excuse her husband's conduct. She depends not upon her own reasonings, but on God's grace, to soften David, and expects that grace would work powerfully. She says that it was below him to take vengeance on so weak and despicable an enemy as Nabal, who, as he would do him no kindness, so he could do him no hurt. She foretells the glorious end of David's present troubles. God will preserve thy life; therefore it becomes not thee unjustly and unnecessarily to take away the lives of any, especially of the people of thy God and Saviour. Abigail keeps this argument for the last, as very powerful with so good a man; that the less he indulged his passion, the more he consulted his peace and the repose of his own conscience. Many have done that in a heat, which they have a thousand times wished undone again. The sweetness of revenge is soon turned into bitterness. When tempted to sin, we should consider how it will appear when we think upon it afterwards.
