1 Kings 11:41

And the rest of the acts of Solomon, and all that he did, and
his wisdom, are they not written in the book of the acts of Solomon?
] Either written by himself, as Kimchi suggests, though not in being; or by some chronologer or historiographer employed by him in writing the most memorable things that happened in his reign; or by several prophets, as in ( 2 Chronicles 9:29 ) out of which the inspired writer of this book took what he was directed to by the Lord to be transmitted to future ages.
