2 Samuel 23:11-15
English Standard Version
Chapter 23
11And next to him was Shammah, the son of Agee the Hararite. The Philistines gathered together at Lehi, where there was a plot of ground full of lentils, and the men fled from the Philistines. 12But he took his stand in the midst of the plot and defended it and struck down the Philistines, and the Lord worked a great victory.
13And three of the thirty chief men went down and came about harvest time to David at the cave of Adullam, when a band of Philistines was encamped in the Valley of Rephaim.
14David was then in the stronghold, and the garrison of the Philistines was then at Bethlehem.
15And David said longingly, "Oh, that someone would give me water to drink from the well of Bethlehem that is by the gate!"
