John Chrysostom — as excerpted in the Catena Aurea on Luke 4:22-27

“(ubi sup.) For though after a long time and when He had begun to shew forth His miracles, He came to them; they did not receive Him, but again were inflamed with envy. Hence it follows, And he said unto them, Ye will surely say unto me this proverb, Physician, heal thyself.”
