[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: 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? they brought it. Therefore he would not drink it. These things did these three mightiest.
