In the four hundred and eightieth year - It is upon this statement that all the earlier portion of what is called the “received chronology” depends. Amid Minor differences there is a general agreement, which justifies us in placing the accession of Solomon about 1000 B.C. (1018 B.C. Oppert.) But great difficulties meet us in determining the sacred chronology anterior to this. Apart from the present statement, the chronological data of the Old Testament are insufficient to fix the interval between Solomon’s accession and the Exodus, since several of the periods which make it up are unestimated. Hence, chronologists have based entirely the “received chronology” upon this verse. But the text itself is not free from suspicion.
(1) it is the sole passage in the Old Testament which contains the idea of dating events from an era.
(2) it is quoted by Origen without the date, and seems to have been known only in this shape to Josephus, to Theophilus of Antioch, and to Clement of Alexandria.
(3) it is hard to reconcile with other chronological statements in the Old and New Testament.
Though the books of Joshua, Judges, and Samuel furnish us with no exact chronology, they still supply important chronological data - data which seem to indicate for the interval between the Exodus and Solomon, a period considerably exceeding 480 years. For the years actually set down amount to at least 580, or, according to another computation, to 600; and though a certain deduction might be made from this sum on account of the round numbers, this deduction would scarcely do more than balance the addition required on account of the four unestimated periods. Again, in the New Testament, Paul (according to the received text) reckons the period from the division of Canaan among the tribes in the sixth year of Joshua Joshua 14:1-15, to Samuel the prophet, at 450 years, which would make the interval between the Exodus and the commencement of the temple to be 579 years. On the whole, it seems, therefore, probable that the words “in the four hundred and eightieth year, etc.,” are an interpolation into the sacred text, which did not prevail generally before the third century of our era.
