2 Chronicles 9:29-30

29People wrote down everything else that Solomon did while he ruled as king, from the beginning to the end. The prophet Nathan wrote them down in his book. The prophet Ahijah who came from Shiloh also wrote them down. The prophet Iddo also wrote about them in his book of the visions that he saw about Nebat's son Jeroboam.

30Solomon ruled over all Israel for 40 years while he lived in Jerusalem.
