Mark 9:11-13

And they asked Him, saying, “Why do the scribes say that Elijah must come first?” Then He answered and told them, “Indeed, Elijah is coming first and restores all things. And how is it written concerning the Son of Man, that He must suffer many things and be treated with contempt? But I say to you that Elijah has also come, and they did to him whatever they wished, as it is written of him.”
