1 Kings 15:29-31

New Living Translation

²⁹ He immediately slaughtered all the descendants of King Jeroboam, so that not one of the royal family was left, just as the Lord had promised concerning Jeroboam by the prophet Ahijah from Shiloh. ³⁰ This was done because Jeroboam had provoked the anger of the Lord, the God of Israel, by the sins he had committed and the sins he had led Israel to commit.

³¹ The rest of the events in Nadab’s reign and everything he did are recorded in The Book of the History of the Kings of Israel.
