Bible Chronology (13) - From Abraham to the Exodus (1)

From the Birth of Abraham to the Exodus is 75 + 430 years = 505 years, of which 15 are unreckoned (from Ismael's conception to Isaac's Birth) making a perfect Great Jubilee Cycle of 490 years. We also study the 430 years of Sojourning of Exodus 12:40-41 and Galatians 3:17.
