there was war
Instead of Rehoboam fourteen MSS., the Arabic, and some copies of the Targum, read Abijam. The Syriac has "Abia, the son of Rehoboam;" and the Editio Princeps of the Vulgate has Abia. This is doubtless the true reading, as otherwise it would be an unnecessary repetition of ch. 14:30, and a repetition which interrupts the history of Abijah: (see 2 Ch 13:3, etc.)
