Joam begat Ozias] Not immediately, for three kings came between, Ahaziah, Joash, and Amaziah, 1 Chron. 3. 11, 12. but mediately, as vers. 1. Luke 1. 5. and 13. 16. John 8. 33, 39. It is likely those three kings are omitted, because Matthew intended to keep within the compasse of fourteen generations here, as well as afterwards. And some think these three kings were omitted, rather then others, because Gods curse lay on Joram for marrying of Ahabs daughter, to the fourth generation, as his blessing was on Jehu for destroying Ahabs posteritie, 2 Kings 10:30.
