'Holiness' in the Bible

And I saw heaven opened, and behold, a white horse, and He who was riding it is called Faithful and True (trustworthy, loyal, incorruptible, steady), and in righteousness He judges and wages war [on the rebellious nations].

and if anyone takes away from or distorts the words of the book of this prophecy, God will take away [from that one] his share from the tree of life and from the holy city (new Jerusalem), which are written in this book.
