1 Kings 15:7
Ver. 7. Now the rest of the acts of Abijam, and all that he did, are they not written in the book of the chronicles of the kings of Judah?.... Which seem to be written by Iddo the prophet, see 2Ch 13:22,
and there was war between Abijam and Jeroboam; and a famous pitched battle between them we read of in 2Ch 13:3.
