Flight to Pella

The fourth-century Church Father Eusebius of Caesarea and Epiphanius of Salamis cite a tradition that before the destruction of Jerusalem in AD 70 the early Christians had been warned to flee to Pella in the region of the Decapolis across the Jordan River.

[3] 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 to a certain town beyond the Jordan called Pella.

Here, those who believed in Christ removed from Jerusalem as if holy men had abandoned the royal city itself and the whole land of Judea.This heresy of the Nazoraeans exists in Beroea in the neighbourhood of Coele Syria and the Decapolis in the region of Pella and in Basanitis in the so-called Kokaba (Chochabe in Hebrew).

And this city is said to be of the Decapolis.The early Apostolic Christians were well aware of Jesus' prophecy in Matthew 24 and Luke 21 regarding the abomination of desolation, the surrounding of Jerusalem by the Roman Army, prior to its destruction.

The army mysteriously retreated, which showed the Christians the sign they were looking for to escape to Pella, before the Romans returned to destroy the city: Matthew 24:15-20 KJV: [15] 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:) [16] then let them which be in Judæa flee into the mountains: [17] let him which is on the house top not come down to take any thing out of his house: [18] neither let him which is in the field return back to take his clothes.
