2 Chronicles 15:9 Commentary - English Annotations on the Holy Bible by Matthew Poole
Out of Simeon; which tribe, though they had their inheritance out of the portion of Judah, did for the generality of them revolt to Jeroboam with the other tribes, as appears from many passages of Scripture; which they might conveniently do, because their portion bordered, as on one side upon that of Judah, so on the other side upon that of Dan; and therefore might indifferently join with the one or other, as they saw fit.
They fell to him, to wit, from the king of Israel.

English Annotations on the Holy Bible by Matthew Poole
Matthew Poole (1624–1679) wrote English Annotations on the Holy Bible, completing the chapters as far as Isaiah 58 before his death in 1679. The rest of the Annotations were completed by friends and colleagues among his Nonconformist brethren. The first printing of the completed edition was in 1685, 2 volumes folio, followed by editions in 1688, 1696 (with valuable chapter outlines added by the editors, Samuel Clark and Edward Veale), and the 4th and definitive edition in 1700, the basis of all others.
