Mark 13:5-8

And Jesus began to say unto them, Take heed that no man lead you astray. Many shall come in my name, saying, I am he; and shall lead many astray. And when ye shall hear of wars and rumors of wars, be not troubled: these things must needs come to pass; but the end is not yet. For nation shall rise against nation, and kingdom against kingdom; there shall be earthquakes in divers places; there shall be famines: these things are the beginning of travail.
