Then the angel showed me the river of life-giving water, sparkling like crystal, flowing from the throne of God and of the Lamb down the middle of its street. On either side of the river grew the tree of life that produces fruit twelve times a year, once each month; the leaves of the trees serve as medicine for the nations. Nothing accursed will be found there anymore. The throne of God and of the Lamb will be in it, and his servants will worship him. They will look upon his face, and his name will be on their foreheads. Night will be no more, nor will they need light from lamp or sun, for the Lord God shall give them light, and they shall reign forever and ever. Blessed are they who wash their robes so as to have the right to the tree of life and enter through its gates.
Revelation 22:1-5, 14
