1 Chronicles 11:17-19

Thomson(i) 17 David longed and said, O that some one would give me some water to drink out of the well of Bethlehem which is by the gate! 18 Upon this the three broke through the camp of the Philistines, and having drawn some water out of the well of Bethlehem by the gate, they took it and came to David. But David would not drink it, but poured it out as a libation to the Lord, 19 and said, God forbid that I should do such a thing! Shall I drink the blood of these men who have jeoparded their lives? Because they had brought it at the hazard of their lives he would not drink it. These things were done by these three worthies.
