About eight days later Jesus took Peter, John, and James up on a mountain to pray. And as he was praying, the appearance of his face was transformed, and his clothes became dazzling white. Suddenly, two men, Moses and Elijah, appeared and began talking with Jesus. They were glorious to see. And they were speaking about his exodus from this world, which was about to be fulfilled in Jerusalem.
Peter and the others had fallen asleep. When they woke up, they saw Jesus’ glory and the two men standing with him. As Moses and Elijah were starting to leave, Peter, not even knowing what he was saying, blurted out, “Master, it’s wonderful for us to be here! Let’s make three shelters as memorials—one for you, one for Moses, and one for Elijah.” But even as he was saying this, a cloud overshadowed them, and terror gripped them as the cloud covered them.
Then a voice from the cloud said, “This is my Son, my Chosen One. Listen to him.” When the voice finished, Jesus was there alone. They didn’t tell anyone at that time what they had seen.
The next day, after they had come down the mountain, a large crowd met Jesus. A man in the crowd called out to him, “Teacher, I beg you to look at my son, my only child. An evil spirit keeps seizing him, making him scream. It throws him into convulsions so that he foams at the mouth. It batters him and hardly ever leaves him alone. I begged your disciples to cast out the spirit, but they couldn’t do it.”
Jesus said, “You faithless and corrupt people! How long must I be with you and put up with you?” Then he said to the man, “Bring your son here.”
As the boy came forward, the demon knocked him to the ground and threw him into a violent convulsion. But Jesus rebuked the evil spirit and healed the boy. Then he gave him back to his father. Awe gripped the people as they saw this majestic display of God’s power.
While everyone was marveling at everything he was doing, Jesus said to his disciples, “Listen to me and remember what I say. The Son of Man is going to be betrayed into the hands of his enemies.” But they didn’t know what he meant. Its significance was hidden from them, so they couldn’t understand it, and they were afraid to ask him about it.
Then his disciples began arguing about which of them was the greatest. But Jesus knew their thoughts, so he brought a little child to his side. Then he said to them, “Anyone who welcomes a little child like this on my behalf welcomes me, and anyone who welcomes me also welcomes my Father who sent me. Whoever is the least among you is the greatest.”
