Mark 9:10-13
9:10 They kept this statement to themselves, discussing what this rising from the dead meant.
9:11 Then they asked him, “Why do the experts in the law say that Elijah must come first?”
9:12 He said to them, “Elijah does indeed come first, and restores all things. And why is it written that the Son of Man must suffer many things and be despised?
9:13 But I tell you that Elijah has certainly come, and they did to him whatever they wanted, just as it is written about him.”
