Rivers of living water

On the last and greatest day of the festival, Jesus stood and said in a loud voice, “Let anyone who is thirsty come to me and drink. Whoever believes in me, as Scripture has said, rivers of living water will flow from within them.” By this he meant the Spirit, whom those who believed in him were later to receive. Up to that time the Spirit had not been given, since Jesus had not yet been glorified.

But you, God, will bring down the wicked into the pit of decay; the bloodthirsty and deceitful will not live out half their days. But as for me, I trust in you.
