John 7:37-39 CSB
On the last and most important day of the festival, Jesus stood up and cried out, “If anyone is thirsty, let him come to me and drink. The one who believes in me, as the Scripture has said, will have streams of living water flow from deep within him.” He said this about the Spirit. Those who believed in Jesus were going to receive the Spirit, for the Spirit had not yet been given because Jesus had not yet been glorified.
