About God's fountain of life:

"In your unfailing love you will lead the people you have redeemed. In your strength you will guide them to your holy dwelling. � The nations will hear and tremble; anguish will grip the people of Philistia. �  How priceless is your unfailing love! Both high and low among men find refuge in the shadow of your wings. �  They feast on the abundance of your house; you give them drink from your river of delights. �  For with you is the fountain of life; in your light we see light. � Continue your love to those who know you, your righteousness to the upright in heart. � May the foot of the proud not come against me, nor the hand of the wicked drive me away. � On the last and greatest day of the Feast, Jesus stood and said in a loud voice, "If anyone is thirsty, let him come to me and drink. � Whoever believes in me, as the Scripture has said, streams of living water will flow from within him." � 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.
