Second Kings is the book of dispersion. We see a kingdom divided and constantly at war with itself. We see the corruption of king after king with only a few good kings showing up occasionally as the Lord works to keep His promise to King David that a king would come from his descendants who would be an everlasting king. As the consequences of their sin, we seek the kingdom to the north exiled to Assyria while the kingdom to the south is later exiled to Babylon and the land that God had promised is left in ruins. A lesson in the kings is that no man can rule and maintain unity like God can.
