John 7:37–39
7:37 Now on the last and greatest day of the feast, Jesus stood and cried out, “If anyone is thirsty, let him come to me and drink!
7:38 He who believes in me, as the Scripture has said, from within him will flow rivers of living water.”
7:39 But he said this about the Spirit, which those believing in him were to receive. For the Holy Spirit was not yet given, because Jesus wasn’t yet glorified.
