15 Now three of the thirty chief men went down to the rock to David, into the cave of Adullam, while the army of the Philistines was camping in the valley of Rephaim.
16 David was then in the stronghold, while the garrison of the Philistines was then in Bethlehem.
17 David had a craving and said, "Oh that someone would give me water to drink from the well of Bethlehem, which is by the gate!"
18 So the three broke through the camp of the Philistines and drew water from the well of Bethlehem which was by the gate, and took it and brought it to David; nevertheless David would not drink it, but poured it out to the Lord;
19 and he said, "Be it far from me before my God that I should do this. Shall I drink the blood of these men who went at the risk of their lives? For at the risk of their lives they brought it." Therefore he would not drink it. These things the three mighty men did.
20 As for Abshai the brother of Joab, he was chief of the thirty, and he swung his spear against three hundred and killed them; and he had a name as well as the thirty.
21 Of the three in the second rank he was the most honored and became their commander; however, he did not attain to the first three.
