2 Samuel 23:12-24
English Standard Version
13And three of the thirty chief men went down and came about harvest time to David at the cave of Adullam, when a band of Philistines was encamped in the Valley of Rephaim.
14David was then in the stronghold, and the garrison of the Philistines was then at Bethlehem.
15And David said longingly, "Oh, that someone would give me water to drink from the well of Bethlehem that is by the gate!"
16Then the three mighty men broke through the camp of the Philistines and drew water out of the well of Bethlehem that was by the gate and carried and brought it to David. But he would not drink of it. He poured it out to the Lord
17and said, "Far be it from me, O Lord, that I should do this. Shall I drink the blood of the men who went at the risk of their lives?" Therefore he would not drink it. These things the three mighty men did.
18Now Abishai, the brother of Joab, the son of Zeruiah, was chief of the thirty. And he wielded his spear against three hundred men and killed them and won a name beside the three.
19He was the most renowned of the thirty and became their commander, but he did not attain to the three.
20And Benaiah the son of Jehoiada was a valiant man of Kabzeel, a doer of great deeds. He struck down two ariels of Moab. He also went down and struck down a lion in a pit on a day when snow had fallen.
21And he struck down an Egyptian, a handsome man. The Egyptian had a spear in his hand, but Benaiah went down to him with a staff and snatched the spear out of the Egyptian 's hand and killed him with his own spear.
22These things did Benaiah the son of Jehoiada, and won a name beside the three mighty men.
23He was renowned among the thirty, but he did not attain to the three. And David set him over his bodyguard.
