Revelation 22:2, 14, 19

through the middle of the street of the city; also, on either side of the river, the tree of life with its twelve kinds of fruit, yielding its fruit each month. 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 that they may enter the city by the gates.

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