Peter and his companions were very sleepy, but when they became fully awake, they saw his glory and the two men standing with him.
As the men were leaving Jesus, Peter said to him, “Master, it is good for us to be here. Let us put up three shelters—one for you, one for Moses and one for Elijah.” (He did not know what he was saying.)
While he was speaking, a cloud appeared and covered them, and they were afraid as they entered the cloud.
A voice came from the cloud, saying, “This is my Son, whom I have chosen; listen to him.”
When the voice had spoken, they found that Jesus was alone. The disciples kept this to themselves and did not tell anyone at that time what they had seen.
The next day, when they came down from the mountain, a large crowd met him.
A man in the crowd called out, “Teacher, I beg you to look at my son, for he is my only child.
A spirit seizes him and he suddenly screams; it throws him into convulsions so that he foams at the mouth. It scarcely ever leaves him and is destroying him.
I begged your disciples to drive it out, but they could not.”
“You unbelieving and perverse generation,” Jesus replied, “how long shall I stay with you and put up with you? Bring your son here.”
Even while the boy was coming, the demon threw him to the ground in a convulsion. But Jesus rebuked the impure spirit, healed the boy and gave him back to his father.
