1-kings 4:1

Solomon, that is, was king over "all Israel" from the first; not like David, who for seven and a half years reigned over Judah only. This feature well introduces the glory of Solomon and the organisation of the court, of which the historian in this chapter intends to give us a general sketch. Solomon constitutes certain "princes" or officers of the first rank, deriving their station from him, and probably holding it during pleasure.

4:1 All Israel - This is spoken with respect to his successors, who were kings only over a part, and that the smallest part of it.
