"And the nations were enraged, and Your wrath came, and the time came for the dead to be judged, and the time to reward Your

-bond-servants the prophets
and
-the saints
and
-those who fear Your name, the small and the great,

and to destroy those who destroy the earth."
(Revelation 11:18 NASB)

as a note on the end of this verse (Rev 11:18) the word "destroy"(diaphtheirō) comes from the same greek root word, phtheirō, used in Genesis 6:12 Septuagint:

Now the earth was corrupt(phtheirō) in the sight of God, and the earth was filled with violence.
(Genesis 6:11 NASB)

phtheirō - destroy, corrupt, spoil
diaphtheirō - to destroy utterly, spoil, corrupt
