David: 2nd Samuel 5
5:1-2
The tribes accept David as king over Israel
Several years had passed and after the long war, and Abner had abandoned his support for Ishbosheth, joining David. Joab took revenge on Abner by killing him for the death of Asahel. Ishbosheth was himself murdered by two of his own captains.
All the tribes sent representatives to David and now accepted him as king of the combined nations of Judah & Israel. The prophecy declared by Samuel in 1st Samuel 16: 11-13 was fulfilled.
5:3
An agreement was made formal in Hebron to make David's kingship official.
5:4-5
David was now 30 years old and he had endured over ten years of persecution and warfare to gain the position promised to him by God through Samuel.
5:6
The Jebusites held Jerusalem, God's Holy City, and called it by the name of Jebus. These were one of the peoples that God had commanded the early Hebrews to remove from the promised land of Canaan (Exodus 23) and they had failed to obey.
These people had heavily fortified the city with thick and tall walls and battle placements to repel any effort to take the city. They were so confident that their walls would save them they placed the blind and lame on the walls to mock the forces of David. But the Lord had plans greater than the walls of the Jebusites.
5:7
The city was to become known as Zion, and this common term is now first seen in scripture as described as having been taken by David. Thereafter, this area will be known as the City of David. Its high point became later the temple mount, where the rock of Abraham's testing was located.
5:8
There was an underground spring flowing under the walls into the city, which was considered secure to water the people in case of siege. The waterway was named the spring of Gihon and it flows still today.
David's men went through the underground tunnel of this waterway and took the city from inside rather than directly attack it from outside.
5:9-12
David renamed that part of the city to be called "City of David" to remind all of who had conquered it. David himself dwelt in that place and Hiram, the king of Tyre sent materials and craftsmen to build David a beautiful home of the finest cedar. David understood his victory and all that had happened to him was the will of the Lord and he exalted the Lord for what had been given him.
Here he was humble and grateful, unlike the arrogance of Saul.
5:13-24
David took wives and concubines from Jerusalem. It is important that we not overlook the fact that this conduct was directly against the word of God as given in Deuteronomy 1 7: 1 7: "Neither shall he multiply wives to himself that his heart turn not away ... ".
The Philistines, who had been content to let Judah & Israel kill each other, now realized that a unified nation.under David was a threat. They decided to bring their army to Jerusalem and attack the new young combined nation and they were soundly defeated by the forces of David in the valley of Rephraim (meaning the valley of giants) which was ironic since David began by fighting a giant.
The Philistines left their own idol god images that they had brought into battle and these were burned by David's army as commanded in Deuteronomy 7:5: " ... burn their graven images with fire ... ".
The next year the Philistines regrouped and attacked again and once more were defeated under God's direction to David.
