2 Samuel 23:13 KJV

11And after him was Shammah the son of Agee the Hararite. And the Philistines were gathered together into a troop, where was a piece of ground full of lentiles: and the people fled from the Philistines.

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!
