Mark 9:1-6

1 And he said to them, "Truly I say to you, that there are some of those standing here who will never experience death until they see the kingdom of God having come with power."

The Transfiguration

2 And after six days, Jesus took along Peter and James and John, and led them to a high mountain by themselves alone. And he was transfigured before them,

3 and his clothing became radiant--extremely white, like no cloth refiner on earth can {make so white}.

4 And Elijah appeared to them together with Moses, and they were talking with Jesus.

5 And Peter answered [and] said to Jesus, "Rabbi, it is good [that] we are here! And let us make three shelters, one for you and one for Moses and one for Elijah."

6 (For he did not know what he should answer, because they were terrified.)
