John 7:37-39

Verse

37 On the last and greatest day of the feast, Jesus stood up and called out in a loud voice, “If anyone is thirsty, let him come to Me and drink. 38 Whoever believes in Me, as the Scripture has said: ‘Streams of living water will flow from within him.’” 39 He was speaking about the Spirit, whom those who believed in Him were later to receive. For the Spirit had not yet been given, because Jesus had not yet been glorified. (BSB)
