John Gill Commentary 2 Samuel 23:22

"These things did Benaiah the son of Jehoiada, and had a name among the three mighty men." — 2 Samuel 23:22 (ASV)

These [things] did Benaiah the son of Jehoiada
Slew a lion, and two lion-like men of Moab, and an Egyptian of a gigantic stature, (2 Samuel 23:20 2 Samuel 23:21):

and had the name among three mighty men;
of which he was one, and Abishai another, the third Asahel, one of the thirty; or was over them, (2 Samuel 23:24), since thirty are reckoned without him. Abarbinel thinks that the third was Adina, the son of Shiza, the Reubenite, (1 Chronicles 11:42); since thirty were with him, and he at the head of them.
