Rehoboam's defection from the Lord, and his humiliation by the Egyptian king Shishak. - Ch2 12:1. The infinitive כּהכין, "at the time of the establishing," with an indefinite subject, may be expressed in English by the passive: when Rehoboam's royal power was established. The words refer back to Ch2 11:17. כּחזקתו, "when he had become strong" (חזקה is a nomen verbale: the becoming strong; cf. Ch2 26:16; Ch2 11:2), he forsook the Lord, and all Israel with him. The inhabitants of the kingdom of Judah are here called Israel, to hint at the contrast between the actual conduct of the people in their defection from the Lord, and the destiny of Israel, the people of God. The forsaking of the law of Jahve is in substance the fall into idolatry, as we find it stated more definitely in Kg1 14:22.
