1 Chronicles 11:5-15 MSG

5 The citizens of Jebus told David, "No trespassing - you can't come here." David came on anyway and captured the fortress of Zion, the City of David.
6 David had said, "The first person to kill a Jebusite will be commander-in-chief." Joab son of Zeruiah was the first; and he became the chief.
7 David took up residence in the fortress city; that's how it got its name, "City of David."
8 David fortified the city all the way around, both the outer bulwarks (the Millo) and the outside wall. Joab rebuilt the city gates.
9 David's stride became longer, his embrace larger - yes, God-of-the-Angel-Armies was with him!
10 These are the chiefs of David's Mighty Men, the ones who linked arms with him as he took up his kingship, with all Israel joining in, helping him become king in just the way God had spoken regarding Israel.
11 The list of David's Mighty Men: Jashobeam son of Hacmoni was chief of the Thirty. Singlehandedly he killed three hundred men, killed them all in one skirmish.
12 Next was Eleazar son of Dodai the Ahohite, one of the Big Three of the Mighty Men.
13 He was with David at Pas Dammim, where the Philistines had mustered their troops for battle. It was an area where there was a field of barley. The army started to flee from the Philistines
14 and then took its stand right in that field - and turned the tide! They slaughtered the Philistines, God helping them - a huge victory.
15 The Big Three from the Thirty made a rocky descent to David at the Cave of Adullam while a company of Philistines was camped in the Valley of Rephaim.
