The necessity of revising the standard secular chronology of Egypt is widely accepted, but efforts to achieve this so far have been inadequate. By recognizing Joseph of the Bible as the famous Imhotep of Egyptian history, and 12th-Dynasty Amenemhat IV as the pharaoh of the Exodus, a drastic shortening and rearranging of the 3rd to 12th Dynasties is indicated, making the chronology of Egypt accord with that of the Bible.
