Luke 21: 5 - 11
5 And as some spoke of the temple, how it was adorned with noble stones and offerings, he said,
6 "As for these things which you see, the days will come when there shall not be left here one stone upon another that will not be thrown down."
7 And they asked him, "Teacher, when will this be, and what will be the sign when this is about to take place?"
8 And he said, "Take heed that you are not led astray; for many will come in my name, saying, `I am he!' and, `The time is at hand!' Do not go after them.
9 And when you hear of wars and tumults, do not be terrified; for this must first take place, but the end will not be at once."
10 Then he said to them, "Nation will rise against nation, and kingdom against kingdom;
11 there will be great earthquakes, and in various places famines and pestilences; and there will be terrors and great signs from heaven.
