The fountain of living waters. 

How precious is Your lovingkindness, O God! Therefore the children of men put their trust under the shadow of Your wings. They are abundantly satisfied with the fullness of Your house, and You give them drink from the river of Your pleasures. For with You is the fountain of life.Thus says the Lord God: “Behold, My servants shall eat, but you shall be hungry; behold, My servants shall drink, but you shall be thirsty.” § Whoever drinks of the water that I shall give him will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life.” § This He spoke concerning the Spirit, whom those believing in Him would receive.Ho! Everyone who thirsts, come to the waters. § The Spirit and the bride say, “Come!” And let him who hears say, “Come!” And let him who thirsts come. Whoever desires, let him take the water of life freely.
