Many scholars assume that all civilised Semitic nations actually took their rise from Arabia and are, as Sprenger[3] phrases it “Bedouin deposits” (“_abgelagerte Beduinen_”). The question of whether, in the last resort, Arabia was the original home of the Semites or whether they migrated thither from Africa in primitive times is not affected by this assumption.[4] In any case the language of the Hebrews and Aramæans still bears traces of the fact that their forefathers were at one time a nomadic race, which (with regard to the former at least) is to some extent confirmed by Old Testament tradition. It is true that wherever we have any historic record the contrast between these civilised peoples and the dwellers in the desert is evident. But we can imagine that the same thing happened with them as we may observe repeatedly in Arab tribes of later days. They press forward, gradually in part and in part rapidly, out of Arabia proper. The Syrian and Mesopotamian deserts, barren as they seem to us, offer the nomads certain advantages over the regions to the south. The rainfall is somewhat more copious. The nomads come into closer contact with settled peoples, and much as the Bedouin (proud of his freedom and happy in his leisure) may look down upon the industrious peasant and even upon the artisan, yet the greater security and the certainty of obtaining daily food prompts him to take to husbandry in the region of verdure when opportunity offers. The process was sometimes accompanied by violence towards the earlier settlers, but it often came about peaceably. Thus one wave of Arabs slowly overtook another. The names which predominate in the older portions of the Old Testament (Ishmaelites, Midianites, etc.) soon fall into the background. The appearance of the name “Arab” may be in itself an indication of the arrival of fresh tribes in these regions. THE ARABS AND THEIR NEIGHBOURS
