1 Chronicles 11:20-21
20-21Abishai brother of Joab was the chief of the Thirty. Singlehandedly he fought three hundred men, and killed the lot, but he never made it into the circle of the Three. He was highly honored by the Thirty—he was their chief—still, he didn't measure up to the Three.
22-25Benaiah son of Jehoiada was a Mighty Man from Kabzeel with many exploits to his credit: he killed two famous Moabites; he climbed down into a pit and killed a lion on a snowy day; and he killed an Egyptian, a giant seven and a half feet tall. The Egyptian had a spear like a ship's boom but Benaiah went at him with a mere club, tore the spear from the Egyptian's hand, and killed him with it. These are some of the things Benaiah son of Jehoiada did. But he was never included with the Three. He was highly honored among the Thirty, but didn't measure up to the Three. David put him in charge of his personal bodyguard.
