37 On the last day of the feast, the great day, Jesus stood up and proclaimed, “If any one thirst, let him come to me and drink. 38 He who believes in me, asq the scripture has said, ‘Out of his heart shall flow rivers of living water.’ ” 39 Now this he said about the Spirit, which those who believed in him were to receive; for as yet the Spirit had not been given, because Jesus was not yet glorified.
