Yes, to flee to the mountains after Rome conquered the Temple. But what of before that? They should have fought BEFORE the Romans stood in the Temple.
Yeshua revealed two major signs that would alert believers to flee: “When ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.” (
Luke 21:20.)
He also said, “When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand
“Then let them which be in Judaea flee into the mountains: “Let him which is on the housetop not come down to take any thing out of his house: “Neither let him which is in the field return back to take his clothes.” (
Matt. 24:15–18.)
Jerusalem was surrounded by Rome, people were eating each other they were starving so bad. Anyone trying to leave Jerusalem were slaughtered. Tacitus wrote that he had heard that 600,000 were besieged in Jerusalem (see Histories, 5:13), whereas Josephus estimates that nearly three million were in the city because of the feast of unleavened bread. He bases his guess on the reported number of sacrifices during the feast. The number 1,100,000 that he gives seems to refer to those who died in all of Judaea. (See Wars of the Jews, 6:9:3.)
There was only one window of escape, so some reason Rome opened up a way of escape, the believers took it as their sign and did flee. Inside the rally cry was to stay and fight to the bitter end. The flight to Pella took place in A.D. 66 during the attack by Gallus.
Eusebius wrote: “The whole body, however, of the church at Jerusalem, having been commanded by a divine revelation, given to men of approved piety there before the war, removed from the city, and dwelt at a certain town beyond the Jordan, called Pella.” Ecclesiastical History, tr. C. F. Crusè, 3d ed., in Greek Ecclesiastical Historians, 6 vols. (London: Samuel Bagster and Sons, 1842), p. 110 (3:5).
Adam Clarke wrote: “It is very remarkable that not a single Christian perished in the destruction of Jerusalem, though there were many there when Cestius Gallus invested the city; and, had he persevered in the siege, he would soon have rendered himself master of it; but, when he unexpectedly and unaccountably raised the siege, the Christians took that opportunity to escape. …
Vespasian was approaching with his army, all who believed in Christ left Jerusalem and fled to Pella, and other places beyond the river Jordan; and so they all marvellously escaped the general shipwreck of their country: not one of them perished.” The New Testament … with a Commentary and Critical Notes, 6 vols. (Nashville: Abingdon Press, n.d.), 5:228–29.
