In the Transfiguration, Jesus took with him three of his disciples: Peter, James, and John. They went up to a mountain, and there Jesus was transfigured before them, with his face shining like the sun and his clothes becoming as white as light. Moses and Elijah also appeared and talked with Jesus. This event was a significant moment in the Gospels, revealing Jesus' divine nature to his closest followers and foreshadowing his eventual glory.
