This Aramaean or, according to the designation of the Occidentals, Syrian stock must have in very early times sent forth from its most ancient settlements about Babylon a colony, probably for the sake of trade, to the northern end of the Arabian gulf; these were the Nabataeans on the Sinaitic peninsula, between the gulf of Suez and Aila, and in the region of Petra (Wadi Mousa).

In their ports the wares of the Mediterranean were exchanged for those of India; the great southern caravan-route, which ran from Gaza to the mouth of the Euphrates and the Persian gulf, passed through the capital of the Nabataeans--Petra--whose still magnificent rock-palaces and rock-tombs furnish clearer evidence of the Nabataean civilization than does an almost extinct tradition.

The leaders of the Pharisees, to whom after the manner of priests the victory of their faction seemed not too dearly bought at the price of the independence and integrity of their country, solicited Aretas the king of the Nabataeans for aid against Aristobulus, in return for which they promised to give back to him all the conquests wrested from him by Jannaeus.

Thereupon Aretas had advanced with, it was said, 50,000 men into Judaea and, reinforced by the adherents of the Pharisees, he kept king Aristobulus besieged in his capital.
Syrian Cities Amidst the system of violence and feud which thus prevailed from one end of Syria to another, the larger cities were of course the principal sufferers, such as Antioch, Seleucia, Damascus, whose citizens found themselves paralysed in their husbandry as well as in their maritime and caravan trade.

The citizens of Byblus and Berytus (Beyrout) were unable to protect their fields and their ships from the Ityraeans, who issuing from their mountain and maritime strongholds rendered land and sea equally insecure.
Those of Damascus sought to ward off the attacks of the Ityraeans and Ptolemaeus by handing themselves over to the more remote kings of the Nabataeans or of the Jews.
