And forty one years reigned he in Jerusalem
Being a good king, had the blessing of a long reign, and reached, and even exceeded, the years of the reigns of David and Solomon:
and his mother's name was Maachah, the daughter of Abishalom;
that is the name of his grandmother, see ( 1 Kings 15:2 ) she is called his mother, not because she brought him forth, but because she brought him up; and this is observed to his commendation, that though he was educated by an idolatrous woman, yet was not corrupted by her as his father was.
