This oppression began with “a new king over Egypt who knew not Joseph.” It is generally held that these words indicate a new dynasty――one royal line superseded by another, perhaps a foreign power coming in to supplant the former dynasty. The points of historic contact between Egyptian and Hebrew chronology may at some future day be adjusted with reasonable certainty. They are not yet. The subject is undergoing a somewhat thorough investigation with some prospect of ultimate success. At present I am not prepared to express positive opinions. Two of the disputed periods in Hebrew chronology are necessarily involved; (a.) The period of the Judges, which as shown above some reduce to 339 years; others extend to 450; (b.) The period of the sojourn in Egypt, made by some 215 years; by others, 430. Some of the theories which attempt to locate this new king of Egypt in his relation to Hebrew history place the Exodus about B. C. 1600; others B. C. 1491. Some put the commencement of the sojourn in Egypt B. C. 2030; others B. C. 1706; yet others B. C. 1815. I have given my reasons for adopting the longer periods. It is possible that Egyptian authorities may yet throw a strong influence upon the decision of these much disputed points of Hebrew chronology. The narrative shows that the Hebrews had become numerically strong and were rapidly growing stronger. Joseph had been dead probably a considerable time and all the men of his generation. Being 39 years old when his father came into Egypt and dying at the age of 110, he lived to protect his people 71 years. Moses was 80 years old when he came before Pharaoh, bearing the command of the Almighty――“Let my people go.” It is probable that the terrible edict to destroy all the male infants did not long precede the birth of Moses. The interval between the death of Joseph and the birth of Moses will depend on the duration of the entire sojourn in Egypt, since from this entire sojourn we must subtract the years of Joseph’s life after the sojourn began and the years of Moses before it closed, _i. e._ 71 + 80 = 151. This sum must be subtracted either from 215, leaving 64; or from 430, leaving 279. The latter I assume to be the true period. It provides abundantly for the great increase of the Hebrew people, and accounts for the fear felt by Egypt’s “new king.” II. MOSES.
