Thirty and seven in all - This reckoning is correct, though only 36 “names” are given, the names of only two of the second triad being recorded, but 31 names are given from 2 Samuel 23:24 to the end, which, added to the two triads, or six, makes 37. Joab as captain of the whole host stands quite alone. In 1 Chronicles 11:41-47; after Uriah the Hittite, there follow sixteen other names, probably the names of those who took the places of those in the former list, who died from time to time, or who were added when the number was less rigidly restricted to thirty.
