A.T. Robertson Commentary Luke 18:31

"And he took unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and all the things that are written through the prophets shall be accomplished unto the Son of man." — Luke 18:31 (ASV)

Took unto him (παραλαβων). Second aorist active participle of παραλαμβανω. Taking along with himself. So Mr 10:32. Matthew 20:17 adds κατ' ιδιαν (apart). Jesus is making a special point of explaining his death to the Twelve.

We go up (αναβαινομεν). Present active indicative, we are going up.

Unto the Son of man (τω υιω του ανθρωπου). Dative case of personal interest. The position is amphibolous and the construction makes sense either with "shall be accomplished" (τελεσθησετα) or "that are written" (τα γεγραμμενα), probably the former. Compare these minute details of the prophecy here (verses 32f.) with the words in Mr 10:33f.; Matthew 20:18f. , which see.
