4 And David and all Israel went to Jerusalem (the same is Jebus); and the Jebusites, the inhabitants of the land, were there. 5 And the inhabitants of Jebus said to David, Thou shalt not come in hither. Nevertheless David took the stronghold of Zion; the same is the city of David. 6 And David said, Whosoever smiteth the Jebusites first shall be chief and captain. And Joab the son of Zeruiah went up first, and was made chief.

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.
