John 7:38-40

³⁸He that believes in Me, as the Scripture has said, out of his belly will flow rivers of living water.”

³⁹(But this He spoke concerning the Spirit, whom those believing in Him were about to receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified).

⁴⁰Therefore many from the crowd, when they heard this saying, said, “Truly this is the Prophet.”
