9 After him was Eleazar the son of Dodai the son of an Ahohite, one of the three mighty men with David, when they defied the Philistines who were there gathered together to battle, and the men of Israel were gone away. 10 He arose, and struck the Philistines until his hand was weary, and his hand froze to the sword; and Yahweh worked a great victory that day; and the people returned after him only to take spoil. 11 After him was Shammah the son of Agee a Hararite. The Philistines were gathered together into a troop, where there was a plot of ground full of lentils; and the people fled from the Philistines.

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.
