1Six days after this, Jesus took Peter, James, and his brother John with him. He led them up a hill by themselves. 2Jesus was changed in front of them. His face was bright like the sun. His clothes were white, like light. 3Then they saw Moses and Elijah talking with Jesus. 4Peter said to Jesus, Lord, this is a good place for us. If you want, we will make three places here, one for you, one for Moses, and one for Elijah. 5While he was saying this, a bright cloud came over them. A voice in the cloud said, This is my dear Son. I am very pleased with him. Listen to him. 6When the disciples heard it, they bowed their faces to the ground. They were very much afraid. 7But Jesus came and touched them. He said, Get up. Do not fear. 8When they looked up, they saw no one but Jesus. 9When they came down the hill, Jesus said to them, Do not tell anyone what you saw. Do not tell it until after the Son of Man has been raised from death. 10The disciples asked him, Why do the scribes say that Elijah must come first? 11Jesus answered, Elijah does come. He will get everything ready. 12I tell you that Elijah has come already. The people did not know him. And they did to him just what they wanted to do. So also the Son of Man will be troubled by them. 13Then the disciples knew that he was talking about John the Baptizer. 14They came to the people. A man came and kneeled in front of Jesus. 15He said, Sir, help my son. A bad spirit is in him and he has much trouble. Often he falls into the fire, and often he falls into the water. 16I brought him to your disciples, but they could not heal him. 17Jesus said, You people today do not believe. You have turned away from God. How long must I be with you? How long must I put up with you? Bring the boy here to me. 18Jesus talked to the bad spirit and he came out of the boy. The boy was healed. 19Then the disciples came to Jesus alone. They asked him, Why could we not drive the bad spirit out? 20Jesus said to them, Because you do not believe enough. I tell you the truth. If your strength to believe were as much as a little mustard seed, you could say to this hill, "Go, move over to that place!" And it would move. Nothing is too hard for you to do. 21But this kind of bad spirit does not come out of a person unless people ask God and fast
