Mark 9:15

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?

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.”

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

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

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

and 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.”
