Rehoboam was forty and one years old; therefore he was born a year before Solomon was king, as appears from 1 Kings 11:42. This is noted as an aggravation of Rehoboam's folly, that he was old enough to have been wiser. An Ammonitess; a people cursed by God, and shut out of the congregation of his people for ever, Deuteronomy 23:3 Nehemiah 13:1. This is observed as one cause both of God's displeasure in punishing Solomon with such a son, and of Rehoboam's apostacy after his three first years, 2 Chronicles 11:17.
