“How then is it written
About the Son of man?
He is to go through
He will be treated
καὶ πῶς γέγραπται ἐπὶ τὸν Υἱὸν τοῦ ἀνθρώπου, ἵνα πολλὰ πάθῃ καὶ ἐξουδενηθῇ;
This verse about the future sufferings of the Son of Man is unique to Mark. Jesus said that it was written (καὶ πῶς γέγραπται) that the Son of man (ἐπὶ τὸν Υἱὸν τοῦ ἀνθρώπου) would go through many great sufferings (ἵνα πολλὰ πάθῃ). He would be despised or treated with contempt (καὶ ἐξουδενηθῇ). Obviously, the Son of Man seemed to be tied in some way with Elijah.
