Exposition of the Old and New Testament, by John Gill, [1746-63], at sacred-texts.com
The ninth chapter is the same with Kg1 10:1 excepting Ch2 9:26, which agrees with Kg1 4:21, the same with Kg1 11:41, only in Ch2 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 Kg1 13:1; the books mentioned are since lost. (b) Sept. de, Junius & Tremellias, Piscator.
