John 7:37-39 - The Promise Of The Spirit
37 Now on the last day, the great day of the feast, Jesus stood up and spake aloud, saying, If any man thirst, let him come unto me and drink. 38 He that believeth on me, as the scripture hath said, from his belly shall rivers flow of living water. 39 (Now he spake this in reference to the Spirit, which they who believe on him should afterwards receive: for as yet the Holy Ghost was not given; because Jesus was not yet glorified.)
