'Dynasty' in the Bible
He followed in the footsteps of the kings of Israel, just as Ahab's dynasty had done, for he married Ahab's daughter. He did evil in the sight of the Lord.
But the Lord was unwilling to destroy Judah. He preserved Judah for the sake of his servant David to whom he had promised a perpetual dynasty.
He followed in the footsteps of Ahab's dynasty and did evil in the sight of the Lord, like Ahab's dynasty, for he was related to Ahab's family.
I will make Ahab's dynasty like those of Jeroboam son of Nebat and Baasha son of Ahijah.
Ahab had seventy sons living in Samaria. So Jehu wrote letters and sent them to Samaria to the leading officials of Jezreel and to the guardians of Ahab's dynasty. This is what the letters said,
pick the best and most capable of your master's sons, place him on his father's throne, and defend your master's dynasty."
Therefore take note that not one of the judgments the Lord announced against Ahab's dynasty has failed to materialize. The Lord had done what he announced through his servant Elijah."
The Lord said to Jehu, "You have done well. You have accomplished my will and carried out my wishes with regard to Ahab's dynasty. Therefore four generations of your descendants will rule over Israel."
He tore Israel away from David's dynasty, and Jeroboam son of Nebat became their king. Jeroboam drove Israel away from the Lord and encouraged them to commit a serious sin.
I will destroy Jerusalem the same way I did Samaria and the dynasty of Ahab. I will wipe Jerusalem clean, just as one wipes a plate on both sides.
