37 Now on the last day, the great [day] of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me and drink. 38 He that believeth on me, as the scripture hath said, from within him shall flow rivers of living water. 39 But this spake he of the Spirit, which they that believed on him were to receive: for the Spirit was not yet [given]; because Jesus was not yet glorified.
