1 Kings 15:25–32
25 Nadab the son of Jeroboam began to reign over Israel in the second year of Asa king of Judah, and he reigned over Israel two years. 26 He did evil in the eyes of Yahweh, and he walked in the way of his father and in his sin that he caused Israel to commit. 27 Baasha son of Ahijah of the house of Issachar conspired against him, and Baasha struck him down at Gibbethon, which belonged to the Philistines. Now Nadab and all of Israel were laying siege to Gibbethon, 28 and Baasha killed him in the third year of Asa the king of Judah, and he reigned in his place. 29 It happened that as soon as he became king, he killed all of the house of Jeroboam. There was no one left of Jeroboam who breathed, until he had destroyed him according to the word of Yahweh that he had spoken by the hand of his servant, Ahijah the Shilonite, 30 because of the sins of Jeroboam that he had committed and that he had caused Israel to commit and because of his anger with which he had provoked Yahweh the God of Israel. 31 Now the remainder of the acts of Nadab and all that he did, are they not written on the scroll of the events of the days of the kings of Israel?
32 There was war between Asa and Baasha king of Israel all their days.
