To couple this with the traditional belief that there was once a person called Moses, would be to misconceive the possible range of oral tradition, and to forget the universal tendency to imagine the ancestors or founders of tribes and races. That there was a clan bearing a name like Mosheh or Moses; that, owing to a close connection with a Yahveh-worshipping tribe of Kenites, this clan became ardently devoted to the service of Yahveh; and that its chief centre was at Zarephath [Sarepta] (whence, be it noted, another prophetic hero of tradition, Elijah, probably sprung), may, however, be admitted as probable. Other kindred clans must have gathered round that which bore the name of Moses, and we find that when the northward migration of those whom we know as Israelites took place, the number of the emigrants was increased by the adhesion of other North Arabians. All who were thus brought together must have had the link of a common worship--the worship of the god called Yahveh, a name which must originally have expressed a physical relation or phenomenon, but which in course of time came to be explained by some as meaning the truly existent or the self-manifesting One. This God was believed to be specially present on Mount Sinai, whence it is natural that the Yahveh-worshipping tribes of Israel conceived themselves to have derived laws and institutions which were really of late origin. The Israelites in Arabia were nomads, but the three great annual festivals referred to in the Pentateuch are those of an agricultural people, and must have been adopted by the Israelites after they had passed into a settled mode of life. One portion of the first of these feasts, however--the so-called Passover--is really a monument of the nomadic life of the Israelites; it corresponds to a similar spring-festival which we know to have been observed by the ancient Arabians. The festival of the New Moon, which was entirely unconnected with agriculture, and that of sheep-shearing, may have been retained by the Israelites from their nomadic period.
