1 Chronicles 11:5-15 NRS

5 The inhabitants of Jebus said to David, "You will not come in here." Nevertheless David took the stronghold of Zion, now the city of David.
6 David had said, "Whoever attacks the Jebusites first shall be chief and commander." And Joab son of Zeruiah went up first, so he became chief.
7 David resided in the stronghold; therefore it was called the city of David.
8 He built the city all around, from the Millo in complete circuit; and Joab repaired the rest of the city.
9 And David became greater and greater, for the Lord of hosts was with him.
10 Now these are the chiefs of David's warriors, who gave him strong support in his kingdom, together with all Israel, to make him king, according to the word of the Lord concerning Israel.
11 This is an account of David's mighty warriors: Jashobeam, son of Hachmoni, a was chief of the Three; b he wielded his spear against three hundred whom he killed at one time.
