Please explain how this is a stretch? Here is what the church historian Eusebius had to say about this event:
"But the people of the church in Jerusalem had been commanded by a revelation, vouchsafed to approved men there before the war, to leave the city and to dwell in a certain town of Perea called Pella. And when those that believed in Christ had come thither from Jerusalem, then, as if the royal city of the Jews and the whole land of Judea were entirely destitute of holy men, the judgment of God at length overtook those who had committed such outrages against Christ and his apostles, and totally destroyed that generation of impious men.
But the number of calamities which everywhere fell upon the nation at that time, the extreme misfortunes to which the inhabitants of Judea were especially subjected, the thousands of men, as well as women and children, that perished by the sword, by famine, and by other forms of death innumerable,—all these things, as well as the many great sieges which were carried on against the cities of Judea, and the excessive sufferings endured by those that fled to Jerusalem itself, as to a city of perfect safety, and finally the general course of the whole war, as well as its particular occurrences in detail, and how at last the abomination of desolation, proclaimed by the prophets, stood in the very temple of God, so celebrated of old, the temple which was now awaiting its total and final destruction by fire,—all these things any one that wishes may find accurately described in the history written by Josephus."
Eusebius: Church History, 3.5.3-4
