'Holiness' in the Bible

The aged women likewise, that they be in behaviour as becometh holiness, not false accusers, not given to much wine, teachers of good things;

For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.

Follow peace with all men, and holiness, without which no man shall see the Lord:

Since all these things are to melt away in this manner, what sort of people must we be, conducting our lives in holiness and godliness,

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.
