Matthew 17:10-12

17:10 The disciples asked him, “Why then do the experts in the law say that Elijah must come first?” 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.”
