Mark 9:11-13

11 They asked Him, saying, "Why is it that the scribes say that ¹Elijah must come first?"

12 And He said to them, "Elijah does first come and restore all things. And yet how is it written of ²the Son of Man that ³He will suffer many things and be treated with contempt?

13 "But I say to you that Elijah has indeed come, and they did to him whatever they wished, just as it is written of him."
