When all the elders of Israel had come to King David at Hebron, he made a compact with them at Hebron before the LORD, and they anointed David king over Israel, as the LORD had promised through Samuel. These were the chiefs of David's mighty men—they, together with all Israel, gave his kingship strong support to extend it over the whole land, as the LORD had promised- this is the list of David's mighty men: Jashobeam, [b] a Hacmonite, was chief of the officers [c] ; he raised his spear against three hundred men, whom he killed in one encounter. One guy with three hundred men and he killed them all? Whoa.
Next to him was Eleazar son of Dodai the Ahohite, one of the three mighty men. He was with David at Pas Dammim when the Philistines gathered there for battle. At a place where there was a field full of barley, the troops fled from the Philistines. But they took their stand in the middle of the field. They defended it and struck the Philistines down, and the LORD brought about a great victory.
Three of the thirty chiefs came down to David to the rock at the cave of Adullam, while a band of Philistines was encamped in the Valley of Rephaim. At that time David was in the stronghold, and the Philistine garrison was at Bethlehem. David longed for water and said, "Oh, that someone would get me a drink of water from the well near the gate of Bethlehem!" So the Three broke through the Philistine lines, drew water from the well near the gate of Bethlehem and carried it back to David. But he refused to drink it; instead, he poured it out before the LORD. "God forbid that I should do this!" he said. "Should I drink the blood of these men who went at the risk of their lives?" Because they risked their lives to bring it back, David would not drink it. Such were the exploits of the three mighty men. So these guys say, 'Hey lets get him a drink of water.' So they break through the whole front line get him a drink and come back. THEN DAVID DOESN'T DRINK IT! That's just plain old rude! They risked thier lives for him and he pours it out. WHY?????
