"He showed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. In the midst of the street, and on either side of the river, is the tree of life, baring twelve manner of fruits, and yielded fruit every month: the leaves of the tree are for the healing of the nations. There shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: they shall see his face; and his name shall be in their foreheads."
