1 Chronicles 11:7-13
English Standard Version
Chapter 11
7And David lived in the stronghold; therefore it was called the city of David. 8And he built the city all around from the Millo in complete circuit, and Joab repaired the rest of the city. 9And David became greater and greater, for the Lord of hosts was with him.
10Now these are the chiefs of David 's mighty men, 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.
11This is an account of David 's mighty men: Jashobeam, a Hachmonite, was chief of the three. He wielded his spear against 300 whom he killed at one time.
