Mark 13:14-23 ASV

Here Jesus describes what it will be like when Rome destroys the temple and crushes Jerusalem. Then Jesus warns people not to believe everyone who will use major events to proclaim that they are the messiah. For example every time something bad happens some people claim it is the end of the world. Also some will use it to their advantage and try to set themselves up as a prophet, or the voice of God, or something else. Don't believe these people.
