8 David fortified the city all the way around, both the outer bulwarks (the Millo) and the outside wall. Joab rebuilt the city gates.

Matthew Henry's Commentary on 1 Chronicles 11:8

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.
