Matthew 26:29 - Ellicott's Commentary On The Whole Bible

I will not drink henceforth of this fruit of the vine. — Literally, product of the vine. It would be better, perhaps, to translate, I shall not drink, as implying the acceptance of what had been ordained by God rather than an act of volition. The words carry us into a region of mystic symbolism. Never afterwards while He tarried upon earth was He to taste of the wine-cup with His disciples. But in the kingdom of God, completed and perfected, He would be with them once again, and then Master and disciples would be alike sharers in that joy in the Holy Ghost, of which wine — new wine — was the appropriate symbol. The language of Proverbs 9:2 and Isaiah 25:6, helps us to enter into the meaning of the words. Even the mocking taunt of the multitude on the day of Pentecost, “These men are full of new wine” (Acts 2:13), may have recalled the mysterious promise to the minds of the Apostles, and enabled them to comprehend that it was through the gift of the Spirit that they were entering, in part at least, even then, into the joy of their Lord.
