The material of this lesson, especially that of chapters 12-13, is important to understanding the rest of Old Testament, for the eighty years that it covers details the split that occurred between the ten tribes of Israel in the north and the tribe of Judah/Benjamin in the south. Since these accounts, like the rest of the Old Testament, were edited many years later (for example, after the return from Babylon) by descendants of those in the southern kingdom, you should think about what their point of view would have been and how that might have shaped their version of the story, the only version we have. There is no factual, objective account of the division, only this one written by someone on one side of the division and later edited by people also on that side of the division. On the other hand, the fact that, apparently, the original writer continually refers to all Israel—both the northern and the southern kingdom—shows that he, at least, was not a simple propagandist for the south. He had the unification of Israel at heart.
After this lesson, the material we read will often not be in chronological order. You can use the Old Testament chronology in the LDS Bible Dictionary to see how the materials we study are related to each other chronologically.
1. Original Israel splits into two factions. The first, in the north, is called Israel and ruled by Jeroboam. The second, Judah, is in the south and ruled by Rehoboam. (1 Kings 12:1-20)
