John 7:38-39

Amplified Bible

³⁸ 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.’”^{(A) 39} 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).
