The purpose of the compiler [of First and Second Kings] was definitely didactic: (1) He judged every king by his conformity or nonconformity to the law of God, especially to the Deuteronomic law of centralized worship. (2) He taught that sin inevitably brings punishment, and faith and righteousness ultimately triumph. (3) He showed an appreciation of the need for social reform, notably in his treatment of Rehoboam and Elijah.
