Mark 9:4-14 MSG

4 Elijah, along with Moses, came into view, in deep conversation with Jesus.
5 Peter interrupted, "Rabbi, this is a great moment! Let's build three memorials - one for you, one for Moses, one for Elijah."
6 He blurted this out without thinking, stunned as they all were by what they were seeing.
7 Just then a light-radiant cloud enveloped them, and from deep in the cloud, a voice: "This is my Son, marked by my love. Listen to him."
8 The next minute the disciples were looking around, rubbing their eyes, seeing nothing but Jesus, only Jesus.
9 Coming down the mountain, Jesus swore them to secrecy. "Don't tell a soul what you saw. After the Son of Man rises from the dead, you're free to talk."
10 They puzzled over that, wondering what on earth "rising from the dead" meant.
11 Meanwhile they were asking, "Why do the religion scholars say that Elijah has to come first?"
12 Jesus replied, "Elijah does come first and get everything ready for the coming of the Son of Man. They treated this Elijah like dirt, much like they will treat the Son of Man, who will, according to Scripture, suffer terribly and be kicked around contemptibly."
14 When they came back down the mountain to the other disciples, they saw a huge crowd around them, and the religion scholars cross-examining them.
