Revelation 22:4 (KJV)

And he shewed 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 of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.

And 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:

And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.

And he said unto me, These sayings are faithful and true: and the Lord God of the holy prophets sent his angel to shew unto his servants the things which must shortly be done.

Behold, I come quickly: blessed is he that keepeth the sayings of the prophecy of this book.

And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things.

Then saith he unto me, See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God.
