John 7:37-39
John 7:37-39 AMP
Now on the last and most important day of the feast, Jesus stood and called out [in a loud voice], “If anyone is thirsty, let him come to Me and drink! He who believes in Me [who adheres to, trusts in, and relies on Me], as the Scripture has said, ‘From his innermost being will flow continually rivers of living water.’ ” [Is 58:11; John 4:14] But He was speaking of the [Holy] Spirit, whom those who believed in Him [as Savior] were to receive afterward. The Spirit had not yet been given, because Jesus was not yet glorified (raised to honor).
