Revelation 22:2, 14, 19

in the middle of its street. On either side of the river was the tree of life, bearing twelve kinds of fruit, yielding its fruit every month; and the leaves of the tree were for the healing of the nations.

Blessed are those who wash their robes, so that they may have the right to the tree of life, and may enter by the gates into the city.

and if anyone takes away from the words of the book of this prophecy, God will take away his part from the tree of life and from the holy city, which are written in this book.
