The ninth chapter is the same with 1Ki 10:1-29 excepting 2Ch 9:26, which agrees with 1Ki 4:21,29-31, the same with 1Ki 11:41-43, only in 2Ch 9:29 it is more largely expressed that the acts of Solomon's reign were written in the book of Nathan the prophet, and in the prophecy of Ahijah the Shilonite, and in the visions of Iddo the seer, against Jeroboam the son of Nebat; or rather "concerning Jeroboam", as the Septuagint and some other versions {b}, in which Iddo is called Joel; and by Theodoret said to be the same that prophesied of Jeroboam and his altar, \\see Gill on "1Ki 13:1"\\; the books mentioned are since lost.
