1 Kings 15:1; 1 Kings 15:7-8

1 In the eighteenth year of the reign of Jeroboam son of Nebat, Abijah became king of Judah,
7 As for the other events of Abijah's reign, and all he did, are they not written in the book of the annals of the kings of Judah? There was war between Abijah and Jeroboam. 8 And Abijah rested with his fathers and was buried in the City of David. And Asa his son succeeded him as king.
