1 Chronicles 11:16-18

16David was then in the stronghold, and the garrison of the Philistines was then in Bethlehem.

17And David said with longing, “Oh, that someone would give me a drink of water from the well of Bethlehem, which is by the gate!”

18So the three broke through the camp of the Philistines, drew water from the well of Bethlehem that was by the gate, and took it and brought it to David. Nevertheless David would not drink it, but poured it out to the Lord.
