2 Chronicles 22:2

2. Forty and two years old was Ahaziah when he began to reign—(Compare :-). According to that passage, the commencement of his reign is dated in the twenty-second year of his age, and, according to this, in the forty-second year of the kingdom of his mother's family [LIGHTFOOT]. "If Ahaziah ascended the throne in the twenty-second year of his life, he must have been born in his father's nineteenth year. Hence, it may seem strange that he had older brothers; but in the East they marry early, and royal princes had, besides the wife of the first rank, usually concubines, as Jehoram had ( :-); he might, therefore, in the nineteenth year of his age, very well have several sons" [KEIL] (compare 2 Chronicles 21:20; 2 Kings 8:17).

Athaliah the daughter of Omri—more properly, "granddaughter." The expression is used loosely, as the statement was made simply for the purpose of intimating that she belonged to that idolatrous race.
