Origen — as excerpted in the Catena Aurea on John 4:31-34

They fear perhaps lest the Word of God, deprived of His own proper nourishment, fail within them; and therefore with such as they have found, immediately propose to feed Him, that being confirmed and strengthened, He may abide with His nourishers.
