[65] When David had cast the Jebusites out of the citadel, he also rebuilt Jerusalem, and named it The City of David, and abode there all the time of his reign; but for the time that he reigned over the tribe of Judah only in Hebron, it was seven years and six months. Now when he had chosen Jerusalem to be his royal city, his affairs did more and more prosper, by the providence of God, who took care that they should improve and be augmented. Hiram also, the king of the Tyrians, sent ambassadors to him, and made a league of mutual friendship and assistance with him. He also sent him presents, cedar-trees, and mechanics, and men skillful in building and architecture, that they might build him a royal palace at Jerusalem. Now David made buildings round about the lower city: he also joined the citadel to it, and made it one body; and when he had encompassed all with walls, he appointed Joab to take care of them. It was David, therefore, who first cast the Jebusites out of Jerusalem, and called it by his own name, The City of David: for under our forefather Abraham it was called (Salem, or) Solyma; ¹ but after that time, some say that Homer mentions it by that name of Solyma, [for he named the temple Solyma, according to the Hebrew language, which denotes security.] Now the whole time from the warfare under Joshua our general against the Canaanites, and from that war in which he overcame them, and distributed the land among the Hebrews, (nor could the Israelites ever cast the Canaanites out of Jerusalem until this time, when David took it by siege,) this whole time was five hundred and fifteen years.
