John 7:37-39

³⁷Now on the last, great day of the festival, Jesus stood and cried out, saying, “If anyone is thirsty, let him come to me and drink.

³⁸He who believes in me, just as the scripture says, rivers of living water will flow from his stomach.”

³⁹But he said this about the Spirit, whom those who believed in him would receive; the Spirit had not yet been given because Jesus was not yet glorified.
