Matthew 17:4-21

4Peter said to Jesus, “Lord, it is good for us to be here. If You wish, I will put up three shelters1—one for You, one for Moses, and one for Elijah.”

5While Peter was still speaking, a bright cloud enveloped them, and a voice from the cloud said, “This is My beloved Son, in whom I am well pleased.2 Listen to Him!” 6When the disciples heard this, they fell facedown in terror.

7Then Jesus came over and touched them. “Get up,” He said. “Do not be afraid.” 8And when they looked up, they saw no one except Jesus.

9As they were coming down the mountain, Jesus commanded them, “Do not tell anyone about this vision until the Son of Man has been raised from the dead.”

10The disciples asked Him, “Why then do the scribes say that Elijah must come first?”

11Jesus replied, “Elijah does indeed come, and he will restore all things. 12But I tell you that Elijah has already come, and they did not recognize him, but have done to him whatever they wished. In the same way, the Son of Man will suffer at their hands.”

13Then the disciples understood that He was speaking to them about John the Baptist.

14When they came to the crowd, a man came up to Jesus and knelt before Him. 15“Lord, have mercy on my son,” he said. “He has seizures and is suffering terribly. He often falls into the fire or into the water. 16I brought him to Your disciples, but they could not heal him.”

17“O unbelieving and perverse generation!” Jesus replied. “How long must I remain with you? How long must I put up with you? Bring the boy here to Me.” 18Then Jesus rebuked the demon, and it came out of the boy, and he was healed from that moment.

19Afterward the disciples came to Jesus privately and asked, “Why couldn’t we drive it out?”

20“Because you have so little faith,” He answered. “For truly I tell you, if you have faith the size of a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”3
