About eight days after these sayings, he took with him Peter, John, and James, and went up onto the mountain to pray. As he was praying, the appearance of his face was altered, and his clothing became white and dazzling. Behold, two men were talking with him, who were Moses and Elijah, who appeared in glory, and spoke of his departure, which he was about to accomplish at Jerusalem.
Now Peter and those who were with him were heavy with sleep, but when they were fully awake, they saw his glory, and the two men who stood with him. As they were parting from him, Peter said to Jesus, “Master, it is good for us to be here. Let’s make three tents: one for you, and one for Moses, and one for Elijah,” not knowing what he said.
While he said these things, a cloud came and overshadowed them, and they were afraid as they entered into the cloud. A voice came out of the cloud, saying, “This is my beloved Son. Listen to him!” When the voice came, Jesus was found alone. They were silent, and told no one in those days any of the things which they had seen.
On the next day, when they had come down from the mountain, a great multitude met him. Behold, a man from the crowd called out, saying, “Teacher, I beg you to look at my son, for he is my only child. Behold, a spirit takes him, he suddenly cries out, and it convulses him so that he foams, and it hardly departs from him, bruising him severely. I begged your disciples to cast it out, and they couldn’t.”
Jesus answered, “Faithless and perverse generation, how long shall I be with you and bear with you? Bring your son here.”
While he was still coming, the demon threw him down and convulsed him violently. But Jesus rebuked the unclean spirit, and healed the boy, and gave him back to his father. They were all astonished at the majesty of God.
But while all were marveling at all the things which Jesus did, he said to his disciples, “Let these words sink into your ears, for the Son of Man will be delivered up into the hands of men.” But they didn’t understand this saying. It was concealed from them, that they should not perceive it, and they were afraid to ask him about this saying.
There arose an argument among them about which of them was the greatest. Jesus, perceiving the reasoning of their hearts, took a little child, and set him by his side, and said to them, “Whoever receives this little child in my name receives me. Whoever receives me receives him who sent me. For whoever is least among you all, this one will be great.”
John answered, “Master, we saw someone casting out demons in your name, and we forbade him, because he doesn’t follow with us.”
Jesus said to him, “Don’t forbid him, for he who is not against us is for us.”
