John 7:37-40

³⁷And on the last, and great day of the festivity, Jesus stood and cried, saying: If any man thirst, let him come to me, and drink.

³⁸He that believeth in me, as the scripture saith, Out of his belly shall flow rivers of living water.

³⁹Now this he said of the Spirit which they should receive, who believed in him: for as yet the Spirit was not given, because Jesus was not yet glorified.

⁴⁰Of that multitude therefore, when they had heard these words of his, some said: This is the prophet indeed.
