1 Chronicles 11:12-21

12 And after him was Eleazar the son of Dodo, the Ahohite, who was one of the three mighties.
13 He was with David at Pasdammim, and there the Philistines were gathered together to battle, where was a parcel of ground full of barley; and the people fled from before the Philistines.
14 And they set themselves in the midst of that parcel, and delivered it, and slew the Philistines; and the LORD saved them by a great deliverance.
15 Now three of the thirty captains went down to the rock to David, into the cave of Adullam; and the host of the Philistines encamped in the valley of Rephaim.
16 And David was then in the hold, and the Philistines' garrison was then at Bethlehem.
17 And David longed, and said, Oh that one would give me drink of the water of the well of Bethlehem, that is at the gate!
18 And the three brake through the host of the Philistines, and drew water out of the well of Bethlehem, that was by the gate, and took it, and brought it to David: but David would not drink of it, but poured it out to the LORD,
19 And said, My God forbid it me, that I should do this thing: 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 these three mightiest.
20 And Abishai the brother of Joab, he was chief of the three: for lifting up his spear against three hundred, he slew them, and had a name among the three.
21 Of the three, he was more honourable than the two; for he was their captain: howbeit he attained not to the first three.
