Jubilees 23:8
7 And his sons Isaac and Ishmael buried him in the double cave, near Sarah his wife, and they wept for him forty days, all the men of his house, and Isaac and Ishmael, and all their sons, and all the sons of Keturah in their places; and the days of weeping for Abraham were ended. 8 And he lived three jubilees and four weeks of years, one hundred and seventy-five years, and completed the days of his life, being old and full of days. 9 For the days of the forefathers, of their life, were nineteen jubilees; and after the Flood they began to grow less than nineteen jubilees, and to decrease in jubilees, and to grow old quickly, and to be full of their days by reason of manifold tribulation and the wickedness of their ways, with the exception of Abraham.
Hebrews 11:9
8 By faith Abraham obeyed when he was called to go out to a place he would later receive as an inheritance, and he went out without understanding where he was going. 9 By faith he lived as a foreigner in the promised land as though it were a foreign country, living in tents with Isaac and Jacob, who were fellow heirs of the same promise. 10 For he was looking forward to the city with firm foundations, whose architect and builder is God.
Notes and References
"... The change in the order of the events can be explained by looking at their dating. In Genesis, the birth of the twins took place when Isaac was sixty years old (Genesis 25:26). Since Abraham was a hundred years old when Isaac was born (Genesis 17:17), he must have been one hundred and sixty years old at the birth of the twins. Abraham died when he was one hundred and seventy-five years old (Genesis 25:7). Thus, according to Genesis, there is an overlap of fifteen years in the lives of Abraham and Jacob. Iin the absolute dating system of Jubilees the birth of Jacob and Esau took place in the second year of the sixth week of the forty-second jubilee (Jubilees 19:13), which is A.M. 2046. Abraham’s death was in the second year of the first week of the forty-third jubilee (Jubilees 22:1), which is a.m. 2060. When one realizes that Abraham was born in A.M. 1876 (compare Jubilees 11:15), it is clear that according to these numbers Abraham must have been one hundred and seventy years old when Jacob and Esau were born, and one hundred and eighty-four years old when he died. Jubilees 23:8, however, takes over the number of one hundred and seventy-five from the Genesis text as Abraham’s age at death. Both in Genesis and in Jubilees the twins were born before Abraham’s death. In the biblical narrative, the story of Abraham is first brought to an end before the birth of Jacob is recounted. By reordering the biblical material, the author of Jubilees is removing a chronological inconsistency in the biblical text. Abraham and Jacob still shared fifteen years together. (Compare Hebrews 11:9, where it is said that Abraham lived in tents with Isaac and Jacob) ..."
