Matthew 17:6-17

And when the disciples heard it, they fell on their faces and were greatly afraid. But Jesus came and touched them and said, “Arise, and do not be afraid.” When they had lifted up their eyes, they saw no one but Jesus only. Now as they came down from the mountain, Jesus commanded them, saying, “Tell the vision to no one until the Son of Man is risen from the dead.” And His disciples asked Him, saying, “Why then do the scribes say that Elijah must come first?” Jesus answered and said to them, “Indeed, Elijah is coming first and will restore all things. But I say to you that Elijah has come already, and they did not know him but did to him whatever they wished. Likewise the Son of Man is also about to suffer at their hands.” Then the disciples understood that He spoke to them of John the Baptist. And when they had come to the multitude, a man came to Him, kneeling down to Him and saying, “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. So I brought him to Your disciples, but 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 bear with you? Bring him here to Me.”
