Continuing the calculations backwards egyptologists sought to establish the date when the Israelites arrived on egypt…the tanach asserts that a stay of 400 years in acord withte Lord’s statement to Abraham…(genesis 15:13-14); also states te book of the new testament Acts 7:6…the book of exodus however says that Israelites dwelt in egypt for 430 years(exodus 12:40-41)…but we know that this too was accounted for because like exodus also states…Joseph and his family the josephites dwelled in egypt before the the arrival of his brothers and their, what was added more to this was the fact that Joseph was made chief of Egypt at thirtyyears old…this leaves intact the 400 years and added to 1433 places the even at 1833 BC…

The next clue is found in Genesis 47:8-9 “And Joseph brought his father and stood hime before the pharoah and the pharoah saidunto Jacob: ‘How old art thou? And jacob answers: My years are one hundred and thirty…placing Jacon’s birth in 1963BC….

Now Isaac was sixty years old when Jacob was born unto him (genesis 6 : 26); and Isaac was born unto his father Abraham when Abraham was 100 years old…Genesis 21 : 5…Abraham who lived to be 175 was 160 years old when his grandon Jacob was born….this places the birth of Abrham in 2123 BC….

The century of Abraham the hundred years from his birth to the birth of his son and successor Isaac-was thus the century that witnessed the rise and fall of the third dynasty of Ur….egyptologists and biblical scholars working together the biblical chronology puts Abraham right un the middle of importanat events along this timeline…not as an observer but as an active participant…
