Has not the scripture said, That Christ comes as the descendant of David, and out of the town of Bethlehem, where David was?
All Commentaries on John 7:42 Go To John 7
Cyril of Alexandria
AD 444
No careless search do the Jews make about Christ, for they were found going through every idea and through varied ideas gathering the perception of the truth. For having first marvelled through His Words, and already taken the eminent confidence of His instructions as a guide to their conjecturing something great about Him, they search besides the Divine Scripture, thinking to find thence a most unerring conception of Him: for so is its nature. That He shall be therefore of the seed of the thrice-blessed David and shall be revealed in Bethlehem of Judaea, they believe, persuaded by the prophecies concerning this. For the Lord sware in truth unto David, saith somewhere the wise Melodist, and will not reject Him, Of the fruit of thy body will I set upon thy throne. And the Prophet saith, And thou Bethlehem house of Ephrata, little art thou to be among the thousands of Judah, for out of thee shall He come forth unto Me to be Ruler of Israel, and His Goings forth from the beginning, from the days of eternity. But the unassisted mind of the Jews was astray and failed of Christ merely on account of Nazareth situate in Galilee, wherein was the common report that our Lord was brought up. For so says one of the holy Evangelists, And He came to Nazareth where He had been brought up. But they not knowing that He had been born in Bethlehem of Judaea of the Holy Virgin which was of the seed of David (for she was of the tribe of Judah by descent), from merely our Lord having been brought up at Nazareth fall away from the truth and miss of sound reasoning.
