2 Samuel 23:15-17

Thomson(i) 15 And David longed and said, Oh that I had some water to drink out of the well which is at Bethlehem; that by the gate! 16 Upon which these three worthies, notwithstanding the garrison of the Philistines then at Bethlehem, broke through the camp of the Philistines, and drew water out of the well at Bethlehem, by the gate. But when they got it, and came to David, he would not drink it, but poured it out as a libation to the Lord, 17 and said, Lord forbid that I should do this. Shall I drink the blood of these men, who have gone at the risk of their lives? So he would not drink it. These exploits were performed by these three men.
