John 7:37-39

21st Century King James Version

³⁷ On the last day, that great day of the feast, Jesus stood and cried out, saying, “If any man thirst, let him come unto Me, and drink.

³⁸ He that believeth in Me, as the Scripture hath said, out of his belly shall flow rivers of living water.”

³⁹ (But this He spoke of the Spirit, whom those who believe in Him should receive; for the Holy Ghost was not yet given, because Jesus was not yet glorified.)
