20 Yehuda and Yisrael were as numerous as the sands of the sea; they ate and drank and were content.

4:20 Yehuda and Yisrael were as numerous as the sands of the sea
Unlike King David who began his rule only over Yehuda, King Shlomo rises to power over a united kingdom comprising all of Yehuda and Yisrael. As Radak notes, everyone in the kingdom recognizes King Shlomo’s rule, due to the universal recognition of his God-given wisdom. The chapter ends with the reward for unity among the People of Israel: they become as numerous as the sand on the sea shore and successful in the Land of Israel, thereby seeing the fulfillment of the blessing Hashem gave to Avraham (Genesis 22:17).
