2 Samuel 23:14-17

14David was then 1in the stronghold, while the garrison of the Philistines was then in Bethlehem. 152David had a craving and said, “Oh that someone would give me water to drink from the well of Bethlehem which is by the gate!” 163So the three mighty men broke through the camp of the Philistines, and drew water from the well of Bethlehem which was by the gate, and took it and brought it to David. Nevertheless he would not drink it, but 4poured it out to the Lord; 17and he said, “Be it far from me, O Lord, that I should do this. 5Shall I drink the blood of the men who went in jeopardy of their lives?” Therefore he would not drink it. These things the three mighty men did.
