"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murderer is less to fear. The traitor is the plague." -Cicero
Speaking Out Against Evil
The Ancient Prophet Isaiah warned:
"Woe to those who call evil good, and good evil; Who put darkness for light, and light for darkness; Who put bitter for sweet, and sweet for bitter!
Woe to those who are wise in their own eyes, And prudent in their own sight!"
A "woe" Biblically speaking is impending Judgement.
