1 Kings 15:29-31

Living Bible

²⁹ He immediately killed all of the descendants of King Jeroboam, so that not one of the royal family was left, just as the Lord had said would happen when he spoke through Ahijah, the prophet from Shiloh. ³⁰ This was done because Jeroboam had angered the Lord God of Israel by sinning and leading the rest of Israel into sin.

³¹ Further details of Baasha’s reign are recorded in The Annals of the Kings of Israel.
