Charles Ellicott Commentary 1 Chronicles 12:28

"and Zadok, a young man mighty of valor, and of his father`s house twenty and two captains." — 1 Chronicles 12:28 (ASV)

And Zadok, a young man mighty of valour. — And Zadok, a youth, a valiant warrior. Perhaps the successor of Abiathar (1 Kings 2:26–27; 1 Kings 4:4), and his father-house (family), twenty-two princes. The sub-clan or family of Eleazar must have been strong at this time to be able to furnish all these captains, and their implied companies of warriors. But the sum total of the Levites is not given.
