Matthew 24:6-8

You will continually hear of wars and rumors of wars. See that you are not frightened, for those things must take place, but that is not yet the end [of the age]. For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places. But all these things are merely the beginning of birth pangs [of the intolerable anguish and the time of unprecedented trouble].
