Luke 21:21  (King James Version)
Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.

Accordingly, when Cestius Gallus came against Jerusalem, and unexpectedly raised the siege, Josephus states, that many of the noble Jews departed out of the city, as out of a sinking ship; and when Vespasian afterwards drew towards it, a great multitude fled to the mountains. And we learn from Eusebius, and Epiphanius, that at this juncture, all who believed in Christ left Jerusalem, and removed to Pella, and other places beyond Jordan; and so escaped the general shipwreck of their country, that we do not read of one who perished in Jerusalem.
