1 Kings 15:27-29
15:27 Baasha son of Ahijah, from the tribe of Issachar, conspired against Nadab and assassinated him in Gibbethon, which was in Philistine territory. This happened while Nadab and all the Israelite army were besieging Gibbethon.
15:28 Baasha killed him in the third year of Asa’s reign over Judah and replaced him as king.
15:29 When he became king, he executed Jeroboam’s entire family. He wiped out everyone who breathed, just as the Lord had predicted through his servant Ahijah the Shilonite.
