2 Chronicles 22:9
And he sought Ahaziah: and they caught him, (for he was hid in Samaria,) and brought him to Jehu: and when they had slain him, they buried him: Because, said they, he is the son of Jehoshaphat, who sought the Lord with all his heart. So the house of Ahaziah had no power to keep still the kingdom.
