8 These are the names of David's mightiest warriors. The first was Jashobeam the Hacmonite, who was leader of the Three -the three mightiest warriors among David's men. He once used his spear to kill 800Â enemy warriors in a single battle. 9 Next in rank among the Three was Eleazar son of Dodai, a descendant of Ahoah. Once Eleazar and David stood together against the Philistines when the entire Israelite army had fled. 10 He killed Philistines until his hand was too tired to lift his sword, and the Lord gave him a great victory that day. The rest of the army did not return until it was time to collect the plunder! 11 Next in rank was Shammah son of Agee from Harar. One time the Philistines gathered at Lehi and attacked the Israelites in a field full of lentils. The Israelite army fled, 12 but Shammah held his ground in the middle of the field and beat back the Philistines. So the Lord brought about a great victory. 13 Once during the harvest, when David was at the cave of Adullam, the Philistine army was camped in the valley of Rephaim. The Three (who were among the Thirty-an elite group among David's fighting men) went down to meet him there. 14 David was staying in the stronghold at the time, and a Philistine detachment had occupied the town of Bethlehem. 15 David remarked longingly to his men, "Oh, how I would love some of that good water from the well by the gate in Bethlehem." 16 So the Three broke through the Philistine lines, drew some water from the well by the gate in Bethlehem, and brought it back to David. But he refused to drink it. Instead, he poured it out as an offering to the Lord . 17 "The Lord forbid that I should drink this!" he exclaimed. "This water is as precious as the blood of these men who risked their lives to bring it to me." So David did not drink it. These are examples of the exploits of the Three.

Commentary on 2 Samuel 23:8-39
(Read 2 Samuel 23:8-39)
David once earnestly longed for the water at the well of Bethlehem. It seems to be an instance of weakness. He was thirsty; with the water of that well he had often refreshed himself when a youth, and it was without due thought that he desired it. Were his valiant men so forward to expose themselves, upon the least hint of their prince's mind, and so eager to please him, and shall not we long to approve ourselves to our Lord Jesus, by ready compliance with his will, as shown us by his word, Spirit, and providence? But David poured out the water as a drink-offering to the Lord. Thus he would cross his own foolish fancy, and punish himself for indulging it, and show that he had sober thoughts to correct his rash ones, and knew how to deny himself. Did David look upon that water as very precious which was got at the hazard of these men's blood, and shall not we much more value those benefits for purchasing which our blessed Saviour shed his blood? Let all beware of neglecting so great salvation.
