1 Chronicles 11:11-20

11And this is the number of the mighty men whom David had: Jashobeam, the son of a Hachmonite, the chief of the thirty; he lifted up his spear against three hundred and slew them at one time. 12And after him was Eleazar the son of Dodo, the Ahohite, who was one of the three mighty men. 13He was with David at Pasdammim, and there the Philistines were gathered together to battle, where was a plot of ground full of barley; and the people fled from before the Philistines. 14And they stood in the midst of the plot, and defended it, and slew the Philistines; and Jehovah saved them by a great victory.

15And three of the thirty chief men went down to the rock to David, into the cave of Adullam; and the host of the Philistines were encamped in the valley of Rephaim. 16And David was then in the stronghold, and the garrison of the Philistines was then in Beth-lehem. 17And David longed, and said, Oh that one would give me water to drink of the well of Beth-lehem, which is by the gate! 18And the three brake through the host of the Philistines, and drew water out of the well of Beth-lehem, that was by the gate, and took it, and brought it to David: but David would not drink thereof, but poured it out unto Jehovah, 19and said, My God forbid it me, that I should do this: shall I drink the blood of these men that have put their lives in jeopardy? for with the jeopardy of their lives they brought it. Therefore he would not drink it. These things did the three mighty men.

20And Abishai, the brother of Joab, he was chief of the three; for he lifted up his spear against three hundred and slew them, and had a name among the three.
