Matthew 17:14-17

14And when they had come to the multitude, a man came to Him, kneeling down to Him and saying,

15“Lord, have mercy on my son, for he is an epileptic and suffers severely; for he often falls into the fire and often into the water.

16So I brought him to Your disciples, but they could not cure him.”

17Then Jesus answered and said, “O faithless and perverse generation, how long shall I be with you? How long shall I bear with you? Bring him here to Me.”
