Mark 9:2-6

2Six days later Jesus took with him Peter, James, and John and led them alone up a high mountain privately. And he was transfigured before them,

3and his clothes became radiantly white, more so than any launderer in the world could bleach them.

4Then Elijah appeared before them along with Moses, and they were talking with Jesus.

5So Peter said to Jesus, “Rabbi, it is good for us to be here. Let us make three shelters – one for you, one for Moses, and one for Elijah.”

6(For they were afraid, and he did not know what to say.)
