1 Kings 15:29 (KJV)

And Baasha the son of Ahijah, of the house of Issachar, conspired against him; and Baasha smote him at Gibbethon, which belonged to the Philistines; for Nadab and all Israel laid siege to Gibbethon.

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

And 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:

Because 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.

Now 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?
