1 Chronicles 11:9-19

9And David became more and more powerful, because the LORD Almighty was with him.

David’s Mighty Warriors 10These were the chiefs of David’s mighty warriors—they, together with all Israel, gave his kingship strong support to extend it over the whole land, as the LORD had promised—

11this is the list of David’s mighty warriors: Jashobeam, Possibly a variant of Jashob-Baal a Hakmonite, was chief of the officers Or Thirty; some Septuagint manuscripts Three (see also 2 Samuel 23:8) ; he raised his spear against three hundred men, whom he killed in one encounter. 12Next to him was Eleazar son of Dodai the Ahohite, one of the three mighty warriors. 13He was with David at Pas Dammim when the Philistines gathered there for battle. At a place where there was a field full of barley, the troops fled from the Philistines.

14But they took their stand in the middle of the field. They defended it and struck the Philistines down, and the LORD brought about a great victory. 15Three of the thirty chiefs came down to David to the rock at the cave of Adullam, while a band of Philistines was encamped in the Valley of Rephaim. 16At that time David was in the stronghold, and the Philistine garrison was at Bethlehem. 17David longed for water and said, “Oh, that someone would get me a drink of water from the well near the gate of Bethlehem!” 18So the Three broke through the Philistine lines, drew water from the well near the gate of Bethlehem and carried it back to David. But he refused to drink it; instead, he poured it out to the LORD .

19“God forbid that I should do this!” he said. “Should I drink the blood of these men who went at the risk of their lives?” Because they risked their lives to bring it back, David would not drink it. Such were the exploits of the three mighty warriors.
