2 Samuel 23:15 - Clarke's commentary and critical notes on the Bible

And David longed, and said, Oh that one would give me drink of the water of the well of Bethlehem, which is by the gate! The water of the well of Bethlehem - This was David's city, and he knew the excellence of the water which was there; and being near the place, and parched with thirst, it was natural for him to wish for a draught of water out of that well. These three heroes having heard it, though they received no command from David, broke through a company of the Philistines, and brought away some of the water. When brought to David he refused to drink it: for as the men got it at the hazard of their lives, he considered it as their blood, and gave thereby a noble instance of self-denial. There is no evidence that David had requested them to bring it; they had gone for it of their own accord, and without the knowledge of David.
