The Israelites declared that they were descended from a particular family. On account of the patriarchal characcter of their old tribal life, it is not a matter of doubt that, as a fact, the tribe did grow out of a single family. The tribal father, Abraham, was without a doubt the head of the small tribe, which through its large family of children developed into different tribes. Only we must not forget that such a tribe could rapidly be enlarged by receiving into it also serfs and clients (compare
Ge 14:14). These last-mentioned also regarded the head of the tribe as their father and considered themselves as his "sons," without really being his descendants. Possibly the tribe that immigrated first to Haran and from there to Canaan was already more numerous than would seem to be the case according to tradition, which takes into consideration only the leading personalities. Secondly, we must remember that the Israelites, because of their patriarchal life, had become accustomed to clothe all the relations of nations to nations in the scheme of the family. In this way such genealogies of nations as are found in
Ge 10 and
11 originated. Here peoples, cities and countries have also been placed in the genealogies, without the author himself thinking of individual persons in this connection, who had borne the names, e.g. of Mizraim (Egypt), Gush (Ethiopia), etc., and were actually sons of Ham. The purpose of the genealogy in this form is to express only the closer or more remote relationship or connection to a group of nations.
Ge 25:1 ff also is a telling example, showing how independently these groups are united. A new wife (Keturah) does not at this place fit into the family history of Abraham. But the writer still wants to make mention of an Arabian group, which was also related to Israel by blood, but in fact stood more distant from the Israelites than did the Ishmaelites. Out of this systematic further development of the living tradition, however, one difficulty arises. It is not in all places easy, indeed not always possible, to draw the line between what is reliable tradition and what is a freer continuation. But it is a misinterpretation of the historical situation, when the entire history of the patriarchs is declared to be incredible, and when in such sharply defined personalities as Abraham, Jacob, Joseph, and others, only personifications of tribes are found, the later history of which tribes is said to be embodied in the lives of these men; e.g. the name Abraham cannot have been the impersonal name of a tribe or of a god. It is found as the name of a person on old Babylonian tablets (Abu ramu); but originally in the nomadic tribe was doubtless pronounced ?abhi ram, i.e. "My father (God) is exalted." The same is true of the name Jacob (really Jakob-el); compare Joseph (Joseph-el), Ishmael, and others, which find their analogies in old Arabian names.
