Mark 9:11

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.

11 They asked him, saying, "Why do the scribes say that Elijah must come first?"

12 He said to them, "Elijah indeed comes first, and restores all things. How is it written about the Son of Man, that he should suffer many things and be despised?

13 But I tell you, that Elijah has come, and they have also done to him whatever they wanted to, even as it is written about him."

14 Coming to the disciples, he saw a great multitude around them, and scribes questioning them.
