2 Samuel 23:14 KJV

12But he stood in the midst of the ground, and defended it, and slew the Philistines: and the LORD wrought a great victory.

13And three of the thirty chief went down, and came to David in the harvest time unto the cave of Adullam: and the troop of the Philistines pitched in the valley of Rephaim.

14And David was then in an hold, and the garrison of the Philistines was then in Bethlehem.

15And David longed, and said, Oh that one would give me drink of the water of the well of Bethlehem, which is by the gate!

16And the three mighty men 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: nevertheless he would not drink thereof, but poured it out unto the LORD.
