A.T. Robertson Commentary John 11:40

"Jesus saith unto her, Said I not unto thee, that, if thou believedst, thou shouldest see the glory of God?" — John 11:40 (ASV)

Said I not unto thee? (Ουκ ειπον σοι; ). Jesus pointedly reminds Martha of his promise to raise Lazarus (verses 25f.).

That if thou believedst (οτ εαν πιστευσηις). Indirect discourse with εαν and the first aorist active subjunctive (condition of third class) retained after the secondary tense ειπον. He had not said this very phrase, εαν πιστευσηις, to Martha, but he did say to her: Πιστευεις τουτο; (Believest thou this?). He meant to test Martha as to her faith already hinted at (verse 22) on this very point. Jesus had also spoken of increase of faith on the part of the disciples (verse 15).

Thou shouldest see the glory of God (οψη την δοξαν του θεου). Future middle indicative of the old defective verb οραω retained in the conclusion of this condition in indirect discourse. Jesus means the glory of God as shown in the resurrection of Lazarus as he had already said to the disciples (verse 4) and as he meant Martha to understand (verse 25) and may in fact have said to her (the report of the conversation is clearly abridged). Hence Bernard's difficulty in seeing how Martha could understand the words of Jesus about the resurrection of Lazarus here and now seems fanciful and far-fetched.
