John Chrysostom — as excerpted in the Catena Aurea on John 7:31-36

“(Hom. 1. 32.) He wants them to think seriously how little time longer He should be with them, and what regret they will feel when He is gone, and they are not able to find Him. I go unto Him that sent Me; this shews that no injury was done Him by their plots, and that His passion was voluntary. The words had some effect upon the Jews, who asked each other, where they were to go, which was like persons desiring to be quit of Him: Then said the Jews among themselves, Whither will He go, that we shall not find Him? Will He go to the dispersed among the Gentiles, and teach the Gentiles? In the fulness of their self-satisfaction, they call them Gentiles, as a term of reproach; the Gentiles being dispersed every where; a reproach which they themselves underwent afterwards. Of old all the nation was united together: but now that the Jews were mixed with the Gentiles in every part of the world, our Lord would not have said, Whither I go, ye cannot come, in the sense of going to the Gentiles.”
