Mark 9:1-8 (NKJV)
1And He said to them, “Assuredly, I say to you that there are some standing here who will not taste death till they see the kingdom of God present with power.”
2Now after six days Jesus took Peter, James, and John, and led them up on a high mountain apart by themselves; and He was transfigured before them. 3His clothes became shining, exceedingly white, like snow, such as no launderer on earth can whiten them. 4And Elijah appeared to them with Moses, and they were talking with Jesus. 5Then Peter answered and said to Jesus, “Rabbi, it is good for us to be here; and let us make three tabernacles: one for You, one for Moses, and one for Elijah”—6because he did not know what to say, for they were greatly afraid.
7And a cloud came and overshadowed them; and a voice came out of the cloud, saying, “This is My beloved Son. Hear Him!” 8Suddenly, when they had looked around, they saw no one anymore, but only Jesus with themselves.
