1 Kings 12:20

Jeroboam was come again. — The assembly at Shechem probably broke up in disorder, carrying everywhere the news of the rebellion. It would be quite in harmony with Jeroboam’s astuteness, if, after setting the revolution on foot, he himself stood aloof from leadership, and waited till “the congregation,” the duly summoned assembly, sent for him and offered him the crown. The title “king over all Israel” certainly indicates a claim on the part of the ten tribes to be the true Israel, relying perhaps on the prophetic choice and blessing of Jeroboam, and professing to have risen in the name of the Lord against the idolatry of Solomon and his house. Perhaps it also indicated a desire for the subjugation of Judah, which Jeroboam, with the aid of Shishak, certainly seems to have subsequently attempted.
