Matthew 17:14–20

And when they came to the crowd, a man came up to him and, kneeling before him, said, “Lord, have mercy on my son, for he has seizures and he suffers terribly. For often he falls into the fire, and often into the water. And I brought him to your disciples, and they could not heal him.” And Jesus answered, “O faithless and twisted generation, how long am I to be with you? How long am I to bear with you? Bring him here to me.” And Jesus rebuked the demon, and it came out of him, and the boy was healed instantly. Then the disciples came to Jesus privately and said, “Why could we not cast it out?” He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”

When they came to the crowd, a man approached Jesus and knelt before him. “Lord, have mercy on my son,” he said. “He has seizures and is suffering greatly. He often falls into the fire or into the water. I brought him to your disciples, but they could not heal him.”

“You unbelieving and perverse generation,” Jesus replied, “how long shall I stay with you? How long shall I put up with you? Bring the boy here to me.” Jesus rebuked the demon, and it came out of the boy, and he was healed at that moment.

Then the disciples came to Jesus in private and asked, “Why couldn’t we drive it out?”

He replied, “Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”

When they reached the crowd, a man approached and knelt down before him. “Lord,” he said, “have mercy on my son, because he has seizures and suffers terribly. He often falls into the fire and often into the water. I brought him to your disciples, but they couldn’t heal him.”

Jesus replied, “You unbelieving and perverse generation, how long will I be with you? How long must I put up with you? Bring him here to me.” Then Jesus rebuked the demon, and it came out of him, and from that moment the boy was healed.

Then the disciples approached Jesus privately and said, “Why couldn’t we drive it out?”

“Because of your little faith,” he told them. “For truly I tell you, if you have faith the size of a mustard seed, you will tell this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”

At the foot of the mountain, a large crowd was waiting for them. A man came and knelt before Jesus and said, “Lord, have mercy on my son. He has seizures and suffers terribly. He often falls into the fire or into the water. So I brought him to your disciples, but they couldn’t heal him.”

Jesus said, “You faithless and corrupt people! How long must I be with you? How long must I put up with you? Bring the boy here to me.” Then Jesus rebuked the demon in the boy, and it left him. From that moment the boy was well.

Afterward the disciples asked Jesus privately, “Why couldn’t we cast out that demon?”

“You don’t have enough faith,” Jesus told them. “I tell you the truth, if you had faith even as small as a mustard seed, you could say to this mountain, ‘Move from here to there,’ and it would move. Nothing would be impossible.”

And when they came to the crowd, a man approached him, kneeling down before him and saying, “Lord, have mercy on my son, because he has seizures and suffers severely, for often he falls into the fire and often into the water. And I brought him to your disciples, and they were not able to heal him.” And Jesus answered and said, “O unbelieving and perverse generation! How long will I be with you? How long must 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 healed from that hour.

Then the disciples approached Jesus privately and said, Why were we not able to expel it?” And he said to them, “Because of your little faith. For truly I say to you, if you have faith like a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”

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. Then came the disciples to Jesus apart, and said, Why could not we cast him out? And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
