John Chrysostom — as excerpted in the Catena Aurea on John 7:40-53

“(Hom. li. 2.) But be it so, they knew not His birth-place: were they ignorant also of His extraction? that He was of the house and family of David? Why did they ask, Hath not the Scripture said, that Christ cometh of the seed of David? They wished to conceal His extraction, and therefore put forward where He had been educated. For this reason, they do not go to Christ and ask, How say the Scriptures that Christ must come from Bethlehem, whereas Thou comest from Galilee? purposely and of malice prepense they do not do this. And because they were thus inattentive, and indifferent about knowing the truth, Christ did not answer them: though He had lauded Nathanael, when he said, Can any good thing come out of Nazareth? and called Him an Israelite indeed, as being a lover of truth, and well learned in the ancient Scriptures.”
