2 Samuel 23
16 Ref And the three men, forcing their way through the Philistine army, got water from the water-hole of Beth-lehem, by the doorway into the town, and took it back to David: but he would not take it, but, draining it out, made an offering of it to the Lord.
17 Ref And he said, Far be it from me, O Lord, to do this; how may I take as my drink the life-blood of men who have put their lives in danger? So he would not take it. These things did the three great men of war.
