2 Samuel 23:8-17

8These are the names of the mighty men whom David had: Joseb-Bassebeth, Tachkemonite the chief of the captains: he was Adino the Eznite; he [fought] against eight hundred, slain [by him] at one time.

9And after him, Eleazar the son of Dodo the son of an Ahohite: he was one of the three mighty men with David, when they had defied the Philistines that were there gathered together to battle, and the men of Israel were gone up.

10He arose and smote the Philistines until his hand was weary, and his hand clave to the sword; and Jehovah wrought a great deliverance that day; and the people returned after him only to spoil.

11And after him, Shammah the son of Agee the Hararite: the Philistines were gathered into a troop, and there was there a plot of ground full of lentils, and the people had fled before the Philistines;

12and he stood in the midst of the plot and delivered it, and smote the Philistines, and Jehovah wrought a great deliverance.

13And three of the thirty chiefs went down, and came to David in the harvest time to the cave of Adullam, when the troop of the Philistines was encamped in the valley of Rephaim.

14And David was then in the stronghold; and the Philistines' garrison was then at Bethlehem.

15And David longed, and said, Oh that one would give me to drink of the water of the well of Bethlehem, which is in the gate!

16And the three mighty men broke through the camp of the Philistines, and drew water out of the well of Bethlehem, which is in the gate, and took it, and brought it to David; however he would not drink of it, but poured it out to Jehovah.

17And he said, Be it far from me, Jehovah, that I should do this thing! is it not the blood of the men that went at the risk of their lives? Therefore he would not drink it. These things did the three mighty men.
