Revelation 22:1-3

He showed me a river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb, in the middle of its street. On this side of the river and on that was the tree of life, bearing twelve kinds of fruits, yielding its fruit every month. The leaves of the tree were for the healing of the nations. There will be no curse any more. The throne of God and of the Lamb will be in it, and his servants will serve him.
