John 7:37-39

LITV(i) 37 And in the last day of the great feast, Jesus stood and cried out, saying, If anyone thirsts, let him come to Me and drink. 38 The one believing into Me, as the Scripture said, Out of his belly will flow rivers of living water. No OT passage 39 But He said this concerning the Spirit, whom the ones believing into Him were about to receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified.
