rwp@Matthew:17:12 @{Elijah is come already} (\Eleias d lthen\). Thus Jesus identifies John the Baptist with the promise in Malachi, though not the real Elijah in person which John denied (John:1:21|). {They knew him not} (\ouk epignsan auton\). Second aorist active indicative of \epiginsk\, to recognize. Just as they do not know Jesus now (John:1:26|). They killed John as they will Jesus the Son of Man.
