Mark 9:9

9 As they were coming down the mountain, he ordered them to tell no one about what they had seen, until after the Son of Man had risen from the dead.

Mark 9:9 In-Context

7 Then a cloud overshadowed them, and from the cloud there came a voice, "This is my Son, the Beloved; listen to him!"
8 Suddenly when they looked around, they saw no one with them any more, but only Jesus.
9 As they were coming down the mountain, he ordered them to tell no one about what they had seen, until after the Son of Man had risen from the dead.
10 So they kept the matter to themselves, questioning what this rising from the dead could mean.
11 Then they asked him, "Why do the scribes say that Elijah must come first?"
