There are a ton o’books that are now lost to us, many of which are mentioned in the Bible. Some of them are:
The Acts of Solomon (1 Kings 11:14)
The Book of the Wars of the Lord (Numbers 21:14)
The Book of Nathan the Prophet (1 Chronicles 29:29)
The Book of Gad the Seer (1 Chronicles 29:29)
The Prophecy of Ahijah the Shilonite (2 Chronicles 9:29)
The Visions of Iddo the Seer (2 Chronicles 9:29)
The Book of Shemaiah the Prophet (2 Chronicles 12:15)
The Chronicle of Jehu, Son of Hanani (2 Chronicles 20:34)
It would be nice to know where we could get copies of these books. The stuff they contain would be priceless. Ah, well—maybe someday somebody will dig up another cache like Qumran. We can only hope.
