It is important to realize what is happening here because what has been set forth now will play out the remainder of Israel/Judah's days. Because of the harsh rule of Judah over the 10 tribes there is a succession led by the exile Jeroboam. A sin is begun that will continued down through every Israel king, a nationalized form of false worship. The Levitical priests are banished and the former Levite cities abandoned. This split was predicted by the prophet Ahijah and confirmed here by God.
While Jeroboam was well aware of why God was choosing to divide the nation because of a particular false worship by Solomon kjv@1Kings:11:31-39, it is of interest that he used the occasion to set up a false worship of his own.
