2 Samuel 23:16

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,

And the three mighty men broke through the host of the Philistines, and drew water out of the well that was in Bethleem in the gate: and they took it, and brought it to David, and he would not drink it, but poured it out before the Lord.
