In the last day, that great day of the feast, Jesus stood and cried, saying,
If any man thirst, let him come unto me, and drink.

But in the last day, the great day of the feast, &c. This was called the day of the assembly or gathering, when the people in a body went to the temple. Christ therefore wished to implant in the people, as they were departing, not merely a longing for Himself, and doubts respecting His religion, but to bring it keenly home to them, just as a preacher should do at the end of his discourse "Since they were going home," says S. Chrysostom, "He gives them saving food for their journey."
Symbolically. The feast of tabernacles was joyful, and thus a type of the resurrection and joy of the blessed, to which Christ just before said He was going. So S. Cyril.
If any one thirst for his own salvation, and a happy and blessed eternity (for these we should especially thirst for and desire, as the highest good), "let him come to Me," i.e, believe in Me, and draw from Me Gospel truth, yea the Holy Spirit Himself, with all His gifts and virtues, for He will lead him to heavenly glory, where all his desires will be fully satisfied (comp. Isaiah 55:1).
