Mark 13:5-8

And Jesus began to say to them, “See to it that no one misleads you. Many will come in My name, saying, ‘I am He!’ and will mislead many. When you hear of wars and rumors of wars, do not be frightened; those things must take place; but that is not yet the end. For nation will rise up against nation, and kingdom against kingdom; there will be earthquakes in various places; there will also be famines. These things are merely the beginning of birth pangs.
