Matthew Poole and continuators on John 6:42

42 And they said, Is not this Jesus the Son of Joseph, whose father and mother we know? How is it then that he saith, I came down from Heaven ?

For Capernaum, where our Saviour now was, was not far from Nazareth, where he had been Educated, and Lived near Thirty Years with Ioseph his reputed Father. Understanding therefore nothing of our Saviours Miraculous Conception by the overshadowing of the Holy Ghost in the Womb of the Virgin; they were much offended at his Discourse of his coming down from Heaven.
