John 7:37-39

YLT(i) 37 And in the last, the great day of the feast, Jesus stood and cried, saying, `If any one doth thirst, let him come unto me and drink; 38 he who is believing in me, according as the Writing said, Rivers out of his belly shall flow of living water;' 39 and this he said of the Spirit, which those believing in him were about to receive; for not yet was the Holy Spirit, because Jesus was not yet glorified.
