Revelation 22:1-2

Then the angel showed me a river of the water of life, clear as crystal, flowing from the throne of God and of the Lamb (Christ), [Ezek 47:1-12] in the middle of its street. On either side of the river was the tree of life, bearing twelve kinds of fruit, yielding its fruit every month; and the leaves of the tree were for the healing of the nations. [Gen 2:9; 3:22]
