Original: The division between 1 and 2 Kings has been made shortly after the deaths of Ahab of the northern kingdom and Jehoshaphat of the southern kingdom. Placing the division at this point causes the account of the reign of Ahaziah of Israel to overlap the end of 1 Kings (22:51 â "53) and the beginning of 2 Kings (chapter 1).
Simplified: 1 and 2 Kings, like 1 and 2 Samuel and 1 and 2 Books of Chronicles) are actually one book.
