And Solomon begat Roboam,.... Called Rehoboam, Kg1 11:43 of Naamah an Ammonitess, Kg1 14:21. And Roboam begat Abia, sometimes called Abijam, as in Kg1 14:31, sometimes Abijah, Ch2 12:16 and sometimes, as here, Abia, Ch1 3:10. Him Rehoboam begat of Maachah, the daughter of Abishalom, Kg1 15:2 called Michaiah, the daughter of Uriel, Ch2 13:2. Maachah and Michaiah being the same name; or else she went by two names, as her father did. And Abia begat Asa, who was a good king; his mother's name is the same with the name of his father's mother; and perhaps it is not his proper mother, but his grandmother who is meant in Kg1 15:10. He is wrongly called Asaph in the Persic and Ethiopic versions, and in one copy.
