Follows Jesus’ prediction that some of the disciples won’t die before seeing Him coming in His kingdom (Matthew 16:28, “Truly I tell you, some who are standing here will not taste death before they see the Son of Man coming in his kingdom.”). Peter, James, and John see Jesus transfigured—radiating the glory of God––while talking with Moses and Elijah. Peter blunders in his attempt to contribute to the moment.
It reads in Matthew 17:1-13

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.” While Peter was still speaking, a bright cloud enveloped them, and a voice from the cloud said, “This is My beloved Son, in whom I am well pleased. Listen to Him!” When the disciples heard this, they fell facedown in terror. Then Jesus came over and touched them. “Get up,” He said. “Do not be afraid.” And when they looked up, they saw no one except Jesus. As they were coming down the mountain, Jesus commanded them, “Do not tell anyone about this vision until the Son of Man has been raised from the dead.”The disciples asked Him, “Why then do the scribes say that Elijah must come first?” Jesus replied, “Elijah does indeed come, and he will restore all things. But I tell you that Elijah has already come, and they did not recognize him, but have done to him whatever they wished. In the same way, the Son of Man will suffer at their hands. “Then the disciples understood that He was speaking to them about John the Baptist.
