Six days later, Jesus takes Peter, James and John up a high mountain, and there he is transfigured before them: his face shines like the sun and his clothes become white as light. Moses and Elijah appear, talking with him. Peter proposes making three tents, and while he is speaking a bright cloud overshadows them and a voice says this is his beloved Son, with whom he is well pleased: listen to him. The disciples fall on their faces, terrified, but Jesus touches them and tells them to rise and not be afraid; when they lift their eyes they see only Jesus. As they come down, Jesus tells them to tell no one the vision until the Son of Man is raised. They ask why the scribes say Elijah must come first, and Jesus answers that Elijah has already come and they did not recognize him, and the disciples understand he means John the Baptist.
When they reach the crowd, a man kneels before Jesus and asks mercy for his son, who has seizures and often falls into fire and water; the disciples could not heal him. Jesus laments the unbelieving generation, rebukes the demon and the boy is healed from that moment. Privately the disciples ask why they could not, and Jesus says it was because of their little faith, and that with faith like a grain of mustard seed they could tell this mountain to move and nothing would be impossible.
In Galilee, Jesus again announces that the Son of Man will be delivered, killed and raised on the third day, and the disciples are greatly distressed. In Capernaum, those who collect the temple tax ask Peter whether his teacher pays it. Jesus shows that the sons of the king are free, but so as not to cause offense he tells Peter to cast a hook into the sea, and in the mouth of the first fish he will find a coin sufficient for both of them.
