4 And David and all Israel went to Jerusalem, that is, Jebus, where the Jebusites were, the inhabitants of the land. 5 The inhabitants of Jebus said to David, "You will not come in here." Nevertheless, David took the stronghold of Zion, that is, the city of David. 6 David said, "Whoever strikes the Jebusites first shall be chief and commander." And Joab the son of Zeruiah went up first, so he became chief. 7 And David lived in the stronghold; therefore it was called the city of David. 8 And he built the city all around from the Millo in complete circuit, and Joab repaired the rest of the city.

Commentary on 1 Chronicles 11:1-9
(Read 1 Chronicles 11:1-9)
David was brought to possess the throne of Israel after he had reigned seven years in Hebron, over Judah only. God's counsels will be fulfilled at last, whatever difficulties lie in the way. The way to be truly great, is to be really useful, to devote all our talents to the Lord.
