Luke 21:20-22

20“But when you see Jerusalem surrounded by [hostile] armies, then understand [with confident assurance] that her complete destruction is near.

21At that time, those who are in Judea must flee to the mountains, and those who are inside the city (Jerusalem) must get out, and those who are [out] in the country must not enter the city;

22for these are days of vengeance [of rendering full justice or satisfaction], so that all things which are written will be fulfilled.
