Origen

“ Wherefore, reserving the more perfect proclamation of the things concerning Him by the Apostles, He commanded His disciples that they should tell no man that He was the Christ; and He prepared them to say that He was the Christ crucified and risen from the dead, “when He began” not only to say, nor even to advance to the point of teaching merely, but “to show” [1] to His disciples that He must go to Jerusalem, etc.; for attend to the expression “show”; because just as sensible things are said to be shown so the things spoken by Him to His disciples are said to be shown by Jesus. ”
