According to the Jewish historian's reckoning, Galilee contained up to 204 cities and villages. Its inhabitants numbered up to four million. Even if one reduces his usual figure for the inhabitants of each smallest village, namely 15,000, Galilee was still, despite its small extent, a very populous land.
Its inhabitants were not all Jews. Among them were many foreigners of Phoenician, Arabian, and even Egyptian origin. They had come to this land long before, some even in the period of Assyrian dominion. Others had been settled there by Syrian rulers.
The exceptional fertility of this land, as well as its convenience for trade, attracted others later too. Many of these settlers had already adopted the Jewish religion.
Under the scepter of one ruler, the Galileans formed one people made up of persons of different religions and different nations. The Israelites among them, even if not more numerous, were in some sense the dominant people under a ruler who held the Jewish faith.
Yet neither the ruler's faith nor the ancient rights which the Jews had to this land, exclusively in relation to all other nations, gave them any advantages over the other settlers.
Thus Galilee may be regarded, with respect to religion, both as a Jewish land and as a pagan land. In this latter meaning it was called Galilee of the nations.
The mingling of Israelites with pagans in Galilee, and their distance from the capital of their faith, left them for the most part ignorant concerning their faith. They were a people sitting in darkness and in the shadow of death.
The Jews proper looked on them with contempt. "No prophet comes from Galilee," and, "Can anything good come from a Galilean city?" These were common sayings among pure Jews.
The Galileans were not rich in teachers. Yet, for that very reason, Jewish teachers had not handed on to them all their errors.
It is true that they shared with the other Jews some prejudices concerning the Messiah. But their prejudices, being prejudices of ignorance, could more easily be effaced than the prejudices of false enlightenment.
The appearance of the Messiah among them had to draw them to Him all the more, because they had formerly stood so low in the opinion of their Jewish compatriots.
For the other inhabitants of Galilee, the pagans, Jesus also could not remain unnoticed, though neither He nor His disciples addressed their teaching specifically to them. For both He and His disciples healed many of their sick.
In this way, among these people also, the activity and preaching of Jesus could not remain without fruit.
The disciples of Jesus were all from Galilee. It was easier for His other followers to accompany Him there on His journeys, to leave their homes, and to gather the seeds of His teaching, which He scattered here and there. The fertility of the land generally secured their sustenance.
These considerations explain to us why the Savior chose Galilee as the principal place of His activity during His public ministry.
Concerning Galilee and its inhabitants according to Strabo: already in Isa 8:23 there is Gelil heiggoiim, that is, "district of the nations," and Γαλιλαία τών αλλοφύλων (1 Macc 5:15). Pagans, or foreigners, were especially numerous in Upper or Northern Galilee.
