Mark 9:11-13

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.”

Matthew 17:11-13

17:11 He answered, “Elijah does indeed come first and will restore all things. 17:12 And I tell you that Elijah has already come. Yet they did not recognize him, but did to him whatever they wanted. In the same way, the Son of Man will suffer at their hands.” 17:13 Then the disciples understood that he was speaking to them about John the Baptist.

Matthew 27:47-49

27:47 When some of the bystanders heard it, they said, “This man is calling for Elijah.” 27:48 Immediately one of them ran and got a sponge, filled it with sour wine, put it on a stick, and gave it to him to drink. 27:49 But the rest said, “Leave him alone! Let’s see if Elijah will come to save him.”
