Mark 9:14

10They kept this saying to themselves, questioning what the “rising from the dead” meant.

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

12He 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?

13But 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.”

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

15Immediately all the multitude, when they saw him, were greatly amazed, and running to him, greeted him.

16He asked the scribes, “What are you asking them?”

17One of the multitude answered, “Teacher, I brought to you my son, who has a mute spirit;

18and wherever it seizes him, it throws him down; and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, and they weren’t able.”
