4 And David and all Israel went to Jerusalem, which is Jebus; where the Jebusites were, the inhabitants of the land. 5 And the inhabitants of Jebus said to David, Thou shalt not come in hither. But David took the stronghold of Zion, which is the city of David. 6 And David said, Whoever smites the Jebusites first shall be chief and captain. And Joab the son of Zeruiah went first up, and was chief. 7 And David dwelt in the stronghold; therefore they called it the city of David. 8 And he built the city round about, even from the Millo round about; and Joab renewed 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.
