24. _Old Testament History and External Evidence._--Thus the Old Testament, the history of the Jews during the first great period, describes the relation of the Hebrews to surrounding peoples, the superiority of Judah over the faithless (north) Israelite tribes, and the reorganization of the Jewish community in and around Jerusalem at the arrival of Ezra with the Book of the Law. The whole gives an impression of unity, which is designed, and is to be expected in a compilation. But closer examination reveals remarkable gaps and irreconcilable historical standpoints. For all serious biblical study, the stages in the growth of the written traditions and the historical circumstances which they imply, must inevitably be carefully considered, and upon the result depends, directly or indirectly, almost every subject of Old Testament investigation. Yet it is impossible to recover with confidence or completeness the development of Hebrew history from the pages of the Old Testament alone. The keen interest taken by the great prophets in the world around them is not prominent in the national records; political history has been subordinated, and the Palestine which modern discovery is revealing is not conspicuous in the didactic narratives. To external evidence one must look, therefore, for that which did not fall within the scope or the horizon of the religious historians. They do not give us the records of the age of the Babylonian monarch Khammurabi (perhaps Amraphel, Gen. xiv.), of the Egyptian conquests in the XVIIIth and following dynasties, or of the period illustrated by the Amarna tablets (§ 3). They treat with almost unique fullness a few years in the middle of the 9th century B.C., but ignore Assyria; yet only the Assyrian inscriptions explain the political situation (§ 10 seq.), and were it not for them the true significance of the 8th-7th centuries could scarcely be realized (§ 15 seq.). It would be erroneous to confuse the extant sources with the historical material which might or must have been accessible, or to assume that the antiquity of the elements of history proves or presupposes the antiquity of the records themselves, or even to deny the presence of some historical kernel merely on account of unhistorical elements or the late dress in which the events are now clothed. External research constantly justifies the cautious attitude which has its logical basis in the internal conflicting character of the written traditions or in their divergence from ascertained facts; at the same time it has clearly shown that the internal study of the Old Testament has its limits. Hence, in the absence of more complete external evidence one is obliged to recognize the limitations of Old Testament historical criticism, even though this recognition means that positive reconstructions are more precarious than negative conclusions.
