Matthew 17:1-9 New International Version (NIV)
17 After six days Jesus took with him Peter, James and John the brother of James, and led them up a high mountain by themselves. 2 There he was transfigured before them. His face shone like the sun, and his clothes became as white as the light. 3 Just then there appeared before them Moses and Elijah, talking with Jesus.
4 Peter said to Jesus, “Lord, it is good for us to be here. If you wish, I will put up three shelters—one for you, one for Moses and one for Elijah.”
5 While he was still speaking, a bright cloud covered them, and a voice from the cloud said, “This is my Son, whom I love; with him I am well pleased. Listen to him!”
6 When the disciples heard this, they fell facedown to the ground, terrified. 7 But Jesus came and touched them. “Get up,” he said. “Don’t be afraid.” 8 When they looked up, they saw no one except Jesus.
9 As they were coming down the mountain, Jesus instructed them, “Don’t tell anyone what you have seen, until the Son of Man has been raised from the dead.”
