2 Samuel 23:16-17

Brake through the host (or, camp ) of the Philistines. The Philistine camp was pitched in the valley of Rephaim, and to reach Bethlehem, which was more than twenty or twenty-five miles distant, these three heroes must pass close to the ground occupied by the enemy. The valley of Rephaim, in fact, extended from Jerusalem to Bethlehem, and, to guard their position, the Philistines held Bethlehem with a strong garrison. Of course the heroes would use every precaution; for to be discovered would be certain death. The story of their perils and presence of mind in danger, and hairbreadth escape, would be full of interest; but we are told only that they succeeded, and returned in safety, bearing their precious burden; but David would not drink, and poured it out unto Jehovah. The word is that used of a sacrificial libation; for David regarded it as holy, and consecrated to God, because it had been bought with blood—at the risk, that is, of the lives of these gallant men. Nothing is recorded in the romances of the Middle Ages, when knightly chivalry was at its height, more gallant and noble than the exploit of these men. And the very essence of its devotion lay in the fact that it was done to gratify a mere sick longing, and therefore out of pure love. Sick, no doubt, David was, and burning with fever; and even more depressed by the apparent hopelessness of his position. The exploit changed the course of his thoughts. What could he not do with such heroes! Though racked during their absence with anxiety and self-reproach, yet on their return he would be dispirited no longer, but filled with confidence. The words, "Shall I drink?" inserted in the Revised Version, have apparently dropped out of the text by accident. They are found in the parallel place in Chronicles, and in the Septuagint and Vulgate here. The Syriac has, "At the peril of their life's blood these men went."
