Matthew 17:10-13

10 And the disciples asked him, "Then why do the scribes say ¹that first Elijah must come?"

11 He answered, "Elijah does come, and ²he will restore all things.

12 But I tell you that Elijah has already come, and they did not recognize him, but ³did to him whatever they pleased. ⁴So also the Son of Man will certainly suffer at their hands."

13 ⁵Then the disciples understood that he was speaking to them of John the Baptist.
