Forty and two years old was Ahaziah when he began to reign, and he reigned one year in Jerusalem. His mother's name also was Athaliah the daughter of Omri.
Forty two years — Some acknowledge an error in the transcribers of the present Hebrew copies, in which language the numeral letters for 22 and 42 are so like, that they might easily be mistaken. For that it was read 22 here, as it is in the book of Kings, in other Hebrew copies, they gather from hence, that it is at this day so read in divers ancient Greek copies, as also in those two ancient translations, the Syriack and the Arabick, and particularly in that most ancient copy of the Syriack which was used by the church of Antioch in the primitive times, and to this day is kept in the church of Antioch.
The daughter — Of Ahab, Omri's Son. Grand-children are often called sons and daughters.
 Wherefore he did evil in the sight of the LORD like the house of Ahab: for they were his counsellors after the death of his father to his destruction.
His father — Who, while he lived, seduced his son himself, and made other evil counsellors unnecessary.
 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.
Ahaziah — Who, tho' wounded, had made an escape, 2 Kings 9:27.
