Forty and two years old. — An error of transcription. 2 Kings 8:26, twenty and two; and so the Syriac and Arabic: the LXX. has “twenty.” Ahaziah could not have been forty when he succeeded, because his father was only forty when he died (2 Chronicles 21:20).
Athaliah the daughter of Omri — i.e., granddaughter, she being daughter of Ahab and Jezebel. Kings adds, “king of Israel,” which the chronicler purposely omits. (Comp. Micah 6:16 : “The statutes of Omri,” “the works of the house of Ahab.”)
