Jehoshaphat is listed in 1 Chronicles 3.10, Joram in 3.11, and Azariah [=Uzziah] in 3.12. Where Matthew has the shorter text (“Uzziah was the father of Jotham”), 1 Chronicles has the longer, “Ahaziah was the father of Joash; Joash was the father of Amaziah; Amaziah was the father of Azariah [=Uzziah]; Azariah was the father of Jotham.” So then, for whatever reason, whether textual (the accidental omission of these three names) or thematic (the intentional omission of names to maintain the schematic arrangement of three groups of fourteen names), Matthew has omitted three names: Ahaziah, Joash, and Amaziah.
