The first difficulty, really historical, which meets us when we open the volume of Scripture, is the shortness of the time into which all history is (or at any rate appears to be) compressed, by the chronological statements, especially those of Genesis. The exodus of the Jews is fixed by many considerations to about the fifteenth or sixteenth century before our era. The period between the Flood and the Exodus, according to the numbers of our English version, but a very little exceeds a thousand years. Consequently, it has been usual to regard Scripture as authoritatively laying it down that all mankind sprang from a single pair within twenty-five or twenty-six centuries of the Christian era, and therefore that all history, and not only so, but all the changes by which the various races of men were formed, by which languages developed into their numerous and diverse types, by which civilization and art emerged and gradually perfected themselves, are shut up within the narrow space of 2,500 or 2,600 years before the birth of our Lord. Now this time is said with reason to be quite insufficient. Egypt and Babylonia have histories, as settled kingdoms, which reach back (according to the most moderate of modern critical historians) to about the time at which the numbers of our English Bible place the Deluge. Considerable diversities of language can be proved to have existed at that date; markedly different physical types appear not much subsequently; civilization in Egypt has, about the Pyramid period, which few now place later than B.C. 2,450, an advanced character; the arts exist nearly in the shape in which they were known in the country at its most flourishing period. Clearly, a considerable space is wanted anterior to the pyramid age for the gradual development of Egyptian life into the condition which the monuments show to have been then reached. This space the numbers of our English Bible do not allow.
