I. David's Reign over Judah. (2 Sam. 1-4.) After the death of Saul, David went from Ziklag to Hebron, and was there accepted as king over the tribe of Judah. His reign lasted for seven years, from 1010 to 1003 B.C. During a part of this time, Ishbosheth, the only remaining son of Saul, was also nominally reigning over a large part of the land, the real power being held by Abner, Saul's general, and the ablest man of his time. War naturally arose, and many battles were doubtless fought, of which but one, at Gibeon, is related. At last, Abner and Ishbosheth were both murdered, though not by David's desire nor with his approbation; and, with one consent, David was accepted as king over all the Twelve Tribes.
II. The Union of Palestine. (2 Sam. 5-7.) David was now ruler over the mountain region only, as Saul had been before him, and in various places were garrisons of the Philistines, and cities held by the Canaanite races. He began by a siege of Jebus, or Jebusi, a fortress of the Jebusites, on the border of Judah and Benjamin. Though deemed impregnable by the natives, it was taken by storm, and, under its new name, Jerusalem, became the capital of the kingdom. The Philistines had been friendly with David in the past, and were perhaps recognized as the "lords paramount" during his reign over Judah; but now they were jealous of his growing power, and, as of old, entered the mountain region with their armies. But in David they met an enemy of a different character from either Samson or Saul. Two battles were fought, both near Jerusalem, at a place called "the Valley [or plain] of the Rephaim"; and in each the Philistines were utterly routed.
David followed up his advantage, after the second victory, by marching down upon the Shefelah and the plain. He took Gath (called Methegammah, "the bridle of the metropolis," in 2 Sam. 8:1), and subjugated the entire Philistine confederacy so completely that thenceforward they ceased to trouble Israel for centuries.
The land was now united, and David turned his attention to the religious reformation of the people, brought the ark from Baale, or Kirjath-jearim, to Jerusalem, planned for the Temple to be built by his successor, and organized the worship on a magnificent scale. (2 Sam. 6, 7.)
III. David's Foreign Conquests. These were not altogether inspired by ambition, but were necessary for the safety of Israel, and to keep its people from the contamination of the idolatry of the surrounding nations. These conquests are indicated by flags on the map, though the precise locations of the battles are not known in all cases. The lands conquered by David were as follows:
COMPARATIVE AREA OF PALESTINE AT DIFFERENT PERIODS.
1. Moab. (2 Sam. 8:2.) It is stated by Josephus, that the cruel treatment of the Moabites (though fully in accord with the customs of Oriental war in that day) was in revenge for the slaughter of David's parents by the king of Moab, an event not mentioned in the Bible.
2. Zobah (2 Sam. 8:3, 4), at that time the principal state between Damascus and the Euphrates.
