1 Kings 15:30

28Even in the third year of Asa king of Judah did Baasha slay him, and reigned in his stead.

29And it came to pass, when he reigned, that he smote all the house of Jeroboam; he left not to Jeroboam any that breathed, until he had destroyed him, according unto the saying of the LORD, which he spake by his servant Ahijah the Shilonite:

30Because of the sins of Jeroboam which he sinned, and which he made Israel sin, by his provocation wherewith he provoked the LORD God of Israel to anger.

31Now the rest of the acts of Nadab, and all that he did, are they not written in the book of the chronicles of the kings of Israel?

32And there was war between Asa and Baasha king of Israel all their days.
