Sort of. He is living in Hebron, and rules over the southern half of the country.
After seven years the leaders of the rest of the country come and install him as king.
Not all the land has been conquered. Right in the middle of their territory, is a fortress, a stronghold of the Jebusites. They know David is a mighty warrior. They also know their city is impregnable.
So they mock David. "Even the disabled and blind can defend this place against David!"
David consults with his "guys." He promises the commander of the army position to the first one in. Joab gets in, and becomes the first general of David's reign.
4 -6 David and all Israel went to Jerusalem (it was the old Jebus, where the Jebusites lived). The citizens of Jebus told David, "No trespassing—you can't come here." David came on anyway and captured the fortress of Zion, the City of David. David had said, "The first person to kill a Jebusite will be commander-in-chief." Joab son of Zeruiah was the first; and he became the chief.
The waterway is mentioned. I think he found the underground tunnel that fed water to the city and used it to penetrate their defenses.
7 -9 David took up residence in the fortress city; that's how it got its name, "City of David." David fortified the city all the way around, both the outer bulwarks (the Millo) and the outside wall. Joab rebuilt the city gates. David's stride became longer, his embrace larger—yes, God-of-the-Angel-Armies was with him!
So what was David's biggest obstacle, became his hallmark. His namesake.
How about you? Facing obstacles.
Wither away? Or Attack?
