Peter and the men with him were sleeping soundly. When they woke up, they saw Jesus' glory and the two men standing with him.
As Moses and Elijah were leaving him, Peter said to Jesus, "Teacher, it's good that we're here. Let's put up three tents--one for you, one for Moses, and one for Elijah." Peter didn't know what he was saying.
While he was saying this, a cloud overshadowed them. They were frightened as they went into the cloud.
A voice came out of the cloud and said, "This is my Son, whom I have chosen. Listen to him!"
After the voice had spoken, they saw that Jesus was alone. The disciples said nothing, and for some time they told no one about what they had seen.
The next day, when they had come down from the mountain, a large crowd met Jesus.
A man in the crowd shouted, "Teacher, I beg you to look at my son. He's my only child.
Whenever a spirit takes control of him, he shrieks, goes into convulsions, and foams at the mouth. After a struggle, the spirit goes away, leaving the child worn out.
I begged your disciples to force the spirit out of him, but they couldn't do it."
Jesus answered, "You unbelieving and corrupt generation! How long must I be with you and put up with you? Bring your son here!"
While he was coming [to Jesus], the demon knocked the boy to the ground and threw him into convulsions. Jesus ordered the evil spirit to leave. He cured the boy and gave him back to his father.
