Revelation 22:1-3

Then he showed me the river of living water, sparkling like crystal, flowing from the throne of God and of the Lamb down the middle of the broad street of the city. The tree of life was on both sides of the river, bearing 12 kinds of fruit, producing its fruit every month. The leaves of the tree are for healing the nations, and there will no longer be any curse. The throne of God and of the Lamb will be in the city, and His slaves will serve Him.
