Matthew 17:14-23

When they came to the crowd, a man came up to Jesus, falling on his knees before Him and saying, “Lord, have mercy on my son, for he is a lunatic and is very ill; for he often falls into the fire and often into the water. I brought him to Your disciples, and they could not cure him.” And Jesus answered and said, “You unbelieving and perverted generation, how long shall I be with you? How long shall I put up with you? Bring him here to Me.” And Jesus rebuked him, and the demon came out of him, and the boy was cured at once. Then the disciples came to Jesus privately and said, “Why could we not drive it out?” And He *said to them, “Because of the littleness of your faith; for truly I say to you, if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible to you. [But this kind does not go out except by prayer and fasting.”] And while they were gathering together in Galilee, Jesus said to them, “The Son of Man is going to be delivered into the hands of men; and they will kill Him, and He will be raised on the third day.” And they were deeply grieved.
