About eight days after Jesus said these things, he took Peter, John, and James, and went up on a mountain to pray.
As he was praying, the appearance of his face changed and his clothes flashed white like lightning.
Two men, Moses and Elijah, were talking with him.
They were clothed with heavenly splendor and spoke about Jesus' departure, which he would achieve in Jerusalem.
Peter and those with him were almost overcome by sleep, but they managed to stay awake and saw his glory as well as the two men with him.
As the two men were about to leave Jesus, Peter said to him, "Master, it's good that we're here. We should construct three shrines: one for you, one for Moses, and one for Elijah"—but he didn't know what he was saying.
Peter was still speaking when a cloud overshadowed them. As they entered the cloud, they were overcome with awe.
Then a voice from the cloud said, "This is my Son, my chosen one. Listen to him!"
Even as the voice spoke, Jesus was found alone. They were speechless and at the time told no one what they had seen.
The next day, when Jesus, Peter, John, and James had come down from the mountain, a large crowd met Jesus.
A man from the crowd shouted, "Teacher, I beg you to take a look at my son, my only child.
Look, a spirit seizes him and, without any warning, he screams. It shakes him and causes him to foam at the mouth. It tortures him and rarely leaves him alone.
I begged your disciples to throw it out, but they couldn't."
Jesus answered, "You faithless and crooked generation, how long will I be with you and put up with you? Bring your son here."
While he was coming, the demon threw him down and shook him violently. Jesus spoke harshly to the unclean spirit, healed the child, and gave him back to his father.
Everyone was overwhelmed by God's greatness. While everyone was marveling at everything he was doing, Jesus said to his disciples,
"Take these words to heart: the Human One is about to be delivered into human hands."
They didn't understand this statement. Its meaning was hidden from them so they couldn't grasp it. And they were afraid to ask him about it.
