2 Kings 9:16, 21b-22; 10:15-19, 30-32

2 Kings 9:16
16 Then he got into his chariot and rode to Jezreel, because Joram was resting there and Ahaziah king of Judah had gone down to see him.

2 Kings 9:21-22
21 “Hitch up my chariot,” Joram ordered. And when it was hitched up, Joram king of Israel and Ahaziah king of Judah rode out, each in his own chariot, to meet Jehu. They met him at the plot of ground that had belonged to Naboth the Jezreelite. 22 When Joram saw Jehu he asked, “Have you come in peace, Jehu?” "How can there be peace,” Jehu replied, “as long as all the idolatry and witchcraft of your mother Jezebel abound?”

2 Kings 10:15-19
15 After he left there, he came upon Jehonadab son of Rekab, who was on his way to meet him. Jehu greeted him and said, “Are you in accord with me, as I am with you?” “I am,” Jehonadab answered. “If so,” said Jehu, “give me your hand.” So he did, and Jehu helped him up into the chariot. 16 Jehu said, “Come with me and see my zeal for the LORD.” Then he had him ride along in his chariot. 17 When Jehu came to Samaria, he killed all who were left there of Ahab’s family; he destroyed them, according to the word of the LORD spoken to Elijah.

Servants of Baal Killed

18 Then Jehu brought all the people together and said to them, “Ahab served Baal a little; Jehu will serve him much. 19 Now summon all the prophets of Baal, all his servants and all his priests. See that no one is missing, because I am going to hold a great sacrifice for Baal. Anyone who fails to come will no longer live.” But Jehu was acting deceptively in order to destroy the servants of Baal.

2 Kings 10:30-32
30 The LORD said to Jehu, “Because you have done well in accomplishing what is right in my eyes and have done to the house of Ahab all I had in mind to do, your descendants will sit on the throne of Israel to the fourth generation.” 31 Yet Jehu was not careful to keep the law of the LORD, the God of Israel, with all his heart. He did not turn away from the sins of Jeroboam, which he had caused Israel to commit. 32 In those days the LORD began to reduce the size of Israel. Hazael overpowered the Israelites throughout their territory
