Heidegger's Bible Handbook: Exodus: The Chronology of Exodus
5. The chronology of the book.
Moreover, Exodus contains the events of nearly one hundred and forty-five years. Which reckoning of the times is thus computed. Joseph died in the year 2369 from the creation of the world. Thence unto the exodus out of Egypt one hundred and forty-four years pass. In the third month of that year was the arrival at mount Sinai. Thence unto the completion of the building of the tabernacle, in which Exodus ends, ten months pass. On the whole, therefore, the Chronology of Exodus is accomplished in one hundred and forty-five years. But from the beginning of the world unto the end of the events described in Exodus two thousand, five hundred and thirteen years passed.
