8 He built up the city all the way around, from the supporting terraces to the surrounding parts, and Joab restored the rest of the city.
9 David steadily grew more powerful, and the Lord of Hosts was with him.
10 The following were the chiefs of David's warriors who, together with all Israel, strongly supported him in his reign to make him king according to the Lord's word about Israel.
