Such are the words which the new king who knew not Joseph, when he came to the throne, spoke to his people with regard to the alien population which had been allowed during a former reign to settle in the land of Goshen, a fruitful district on the north-east of Egypt, east of Bubastis (Zakāzik). It is the speech of one who feared that, if nothing were done to prevent them from becoming too powerful, they would be a source of danger to the state, as they might join, with every chance of success, in any attack which might be made on the kingdom over which he ruled. It was, in all probability, the presence of a similar foreign (Semitic) population in or near this district, about 2100 years B.C., which had contributed—or perhaps even made—the success of the Hyksos invaders, through which Egypt had been ruled by an alien dynasty for five hundred years. The repetition of such a catastrophe was at all hazards to be prevented. It would seem, therefore, that the persecution of the Hebrews was not undertaken altogether wantonly, but with the object of turning aside a possible misfortune. As the historical nature of the Exodus has not as yet been absolutely disproved, it is here taken to be a matter of history, and this being the case, it is necessary to try to identify, or, rather, to state what are the most probable opinions, as to the rulers of Egypt at the time of the Oppression and the Exodus. Ramses II. of the nineteenth dynasty is generally held to be the Pharaoh of the Oppression, and Meneptah, his son and successor, the Pharaoh of the Exodus. Lieblein, however, would regard this latter event as having occurred during the reign either of Amenophis III., or his son, Amenophis IV., of the eighteenth dynasty. This latter theory is based on the Tel-el-Amarna letters, which speak of the Ḫabiri, roving bodies of men which went about Palestine stirring up the people, and even compelling them by force to renounce Egyptian rule (which extended in those days over the whole of this district). It will be part of the scope of the present work to examine into this question.
