1 Chronicles 11:16

And they set themselves in the midst of that parcel, and delivered it, and slew the Philistines; and the LORD saved them by a great deliverance.

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.

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!

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: but David would not drink of it, but poured it out to the LORD.
