Mark 9:11-13

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

12“Elijah does come first and restores all things,” he replied. “Why then is it written that the Son of Man must suffer many things and be treated with contempt?

13But I tell you that Elijah has come, and they did whatever they pleased to him, just as it is written about him.”
