Expositor's Bible Commentary Commentary Matthew 17:12

"but I say into you, that Elijah is come already, and they knew him not, but did unto him whatsoever they would. Even so shall the Son of man also suffer of them." — Matthew 17:12 (ASV)

Jesus answers the concerns of his disciples. On the one hand, Elijah comes first and “will restore all things”; John’s mission was a success (3:5–6; 14:5). On the other hand, “restore all things” must not be taken absolutely. The Baptist (Elijah) did fulfill his mission, but he was killed doing it. “In the same way the Son of Man is going to suffer at their hands.” If the Baptist’s restoration of “all things” did not prevent his own death, why should Messiah be any better received?
