2 Samuel 23:11-17

11Now after him was Shammah the son of Agee a 1Hararite. And the Philistines were gathered 2into a troop where there was a plot of ground full of lentils, and the people fled from the Philistines. 12But he took his stand in the midst of the plot, defended it and struck the Philistines; and 3the Lord brought about a great 4victory.

13Then three of the thirty chief men went down and came to David in the harvest time to the 5cave of Adullam, while the troop of the Philistines was camping in 6the valley of Rephaim. 14David was then 7in the stronghold, while the garrison of the Philistines was then in Bethlehem. 158David had a craving and said, “Oh that someone would give me water to drink from the well of Bethlehem which is by the gate!” 169So 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 10poured it out to the Lord; 17and he said, “Be it far from me, O Lord, that I should do this. 11Shall 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.
