[1] From the use of the expression "city of the Lord," it has been inferred by some critics that this Psalm must have been written after the capture and consecration of Jerusalem. But there is no reason why Hebron might not have been called at that time "the city of the Lord." The Lord had specially designated it as the abode of David; and that alone entitled it to be so called. Those who have regarded this Psalm as a picture of a model household or family have never weighed the force of the last line, which marks the position of a king, not a father. The Psalm is a true statement of the principles usually followed by David in public rule, but not in domestic administration.
2 SAMUEL ii. 12-32
The well-meant and earnest efforts of David to ward off strife and bring the people together in recognising him as king were frustrated, as we have seen, through the efforts of Abner. Unmoved by the solemn testimony of God, uttered again and again through Samuel, that He had rejected Saul and found as king a man after His own heart; unmoved by the sad proceedings at Endor, where, under such awful circumstances, the same announcement of the purpose of the Almighty had been repeated; unmoved by the doom of Saul and his three sons on Mount Gilboa, where such a striking proof of the reality of God's judgment on his house had been given; unmoved by the miserable state of the kingdom, overrun and humiliated by the Philistines and in the worst possible condition to bear the strain of a civil war,--this Abner insisted on setting up Ishbosheth and endeavouring to make good his claims by the sword. It was never seen more clearly how "one sinner destroyeth much good."
As to the immediate occasion of the war, David was quite innocent, and Abner alone was responsible; but to a feeling and patriotic heart like David's, the war itself must have been the occasion of bitter distress Did it ever occur to him to think that in a sense he was now brought, against his will, into the position which he had professed to King Achish to be willing to occupy, or that, placed as he now was in an attitude of opposition to a large section of his countrymen, he was undergoing a chastisement for what he was rash enough to say and to do then?
In the commencement of the war, the first step was taken by Abner. He went out from Mahanaim, descended the Jordan valley, and came to Gibeon, in the tribe of Benjamin, a place but a few miles distant from Gibeah, where Saul had reigned. His immediate object probably was to gain such an advantage over David in that quarter as would enable him to establish Ishbosheth at Gibeah, and thus bring to him all the prestige due to the son and successor of Saul. We must not forget that the Philistines had still great influence in the land, and very likely they were in possession of Gibeah, after having rifled Saul's palace and appropriated all his private property. With this powerful enemy to be dealt with ultimately, it was the interest of Abner to avoid a collision of the whole forces on either side, and spare the slaughter which such a contest would have involved. There is some obscurity in the narrative now before us, both at this point and at other places. But it would appear that, when the two armies were ranged on opposite sides of the "pool" or reservoir at Gibeon, Abner made the proposal to Joab that the contest should be decided by a limited number of young men on either side, whose encounter would form a sort of play or spectacle, that their brethren might look on, and, in a sense, enjoy. In the circumstances, it was a wise and humane proposal, although we get something of a shock from the frivolous spirit that could speak of such a deadly encounter as "play."
