Mark 9:7

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

5 Peter answered Jesus, "Rabbi, it is good for us to be here. Let`s make three tents: one for you, one for Moses, and one for Elijah."

6 For he didn`t know what to say, for they were very afraid.

7 A cloud came, overshadowing them, and a voice came out of the cloud, "This is my beloved Son. Listen to him."

8 Suddenly looking around, they saw no one with them any more, except Jesus only.

9 As they were coming down from the mountain, he charged them that they should tell no one what things they had seen, until the Son of Man had risen again from the dead.

10 They kept the saying, questioning among themselves what the rising again from the dead should mean.
