If there was one event in David’s life that stood out as his greatest moment, it was probably the conquest of Jerusalem. It’s likely that victory over the Jebusites, the people of Jerusalem, was considered impossible because of the strategic location of the city on a rise that was surrounded on three sides by deep valleys.
Jerusalem was the ultimate strong hold or fortress. It had been occupied for approximately 2000 years, since the time of Abraham, and at least two previous attempts to overtake it had failed. After conquering it, David renamed it the city of David (2 Samuel 5:7).
The capture of Jerusalem was probably important to David because he felt God was using him to establish a permanent kingdom on earth. David believed there would be a Messiah and may have known that Jerusalem would be the capitol from which he would rule and reign over his kingdom. Possession of Jerusalem was therefore and integral part of God’s redemptive program for Israel.
It says in 2 Samuel 5:6, “And David went on and grew great, and the LORD God of hosts was with him.” The term LORD God of hosts is used several times by David in his prayers for deliverance from his enemies. Although it is possible the hosts David was referring to were troops under his command, it s likely David was asking for help with spiritual warfare.
There are some battles that take involve both physical and spiritual warfare. Jerusalem was a key city in the Promised Land, but it is also described as a heavenly city. In Revelation 3:12, it says, “I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God.”
When Jacob was fleeing from his brother Esau, it says in Genesis 28:11 that he came to a certain place. “And he dreamed, and behold a ladder set up on the earth, and the top reached to heaven: and behold the angels of God ascending and descending on it” (Genesis 28:12). The place Jacob came to might have been a portal between the physical and spiritual worlds that enabled him to see what is normally outside of human perception.
One of the unique characteristics of king David was his awareness of the spiritual realm that existed around him. He often spoke to the LORD as if he was standing right next to him. When it says that the LORD God of hosts was with him, I believe it is saying that the LORD God of hosts, super human beings including God and his angels (430), were David’s constant companions.
