The things Rehoboam did as king, from the beginning to the end, are written in the records of Shemaiah the prophet and Iddo the seer, in the family histories. There were wars between Rehoboam and Jeroboam all the time they ruled.
The other things Jehoshaphat did as king, from the beginning to the end, are written in the records of Jehu son of Hanani, which are in the book of the kings of Israel.
Jehoram was thirty-two years old when he became king, and he ruled eight years in Jerusalem. No one was sad when he died. He was buried in Jerusalem, but not in the graves for the kings.
