Jerome
Catena Aurea · Matthäusevangelium 17
And when they were come to the multitude, there came to him a certain man, kneeling down to him, and saying, Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water. And I brought him to thy disciples, and they could not cure him. Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me. And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour.
Not that we must think that He was overcome by weariness of them, and that The meek and gentle broke out into words of wrath, but as a physician who might see the sick man acting against his injunctions, would say, How long shall I frequent your chamber? How long throw away the exercise of my skill, while I prescribe one thing, and you do another? That it is the sin, and not the man with whom He is angry, and that in the person of this one man He convicts the Jews of unbelief, is clear from what He adds, Bring him to me.
