37 In the last day, that great day of the feast, Jesus stood and cried out, saying, If any man thirsts, let him come unto me and drink. 38 He that believes in me, as the scripture has said, out of his belly shall flow rivers of living water. 39 (But this he spoke concerning the Spirit, which those that believe on him should receive, for the Holy Spirit was not yet given because Jesus was not yet glorified.)
