2 Chronicles 22:8-10

American Standard Version

⁸ And it came to pass, when Jehu was executing judgment upon the house of Ahab, that he found the princes of Judah, and the sons of the brethren of Ahaziah, ministering to Ahaziah, and slew them. ⁹ And he sought Ahaziah, and they caught him (now he was hiding in Samaria), and they brought him to Jehu, and slew him; and they buried him, for they said, He is the son of Jehoshaphat, who sought Jehovah with all his heart. ^[a]And the house of Ahaziah had no power to hold the kingdom.

¹⁰ Now when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal of the house of Judah.
