“Ironically, even under such a king as Rehoboam it is the nation of Judah which remains somewhat faithful to God. In the north, Jeroboam quickly leads Israel into idolatry, and over the next 25 years Israel will prove to be so wicked that even self-proclaimed prophets of God will be seen lying to each other. The Levites, and others who are righteous in Israel, are forced southward to join with the people of Judah.
Civil conflict will last for years, as will wars with foreign enemies, who are quick to notice the vulnerability of this once-unified but now-broken people. And Judah, as well as Israel, will turn its face to idolatry.”
