As said before, the year of the Exodus was
1445 BC. Now tracing this back to Bethel is as follows: Jacob entered Egypt four hundred and thirty years before the Exodus.
(1875BC) It was two years into a severe region-wide famine in which many foreigners came to purchase food that the Egyptians had in storage. The Egyptian surplus was accumulated for seven years prior to the start of the drought following the appointment of Joseph as Prime Minister. It resulted from his policies during those seven years of abundance. Therefore the promotion of Joseph was in the year
1884 BC. Further to this, we are told the age of Joseph at his appointment was thirty years. (Gen 41:46) This dates his birth at
1914 BC.
Now the circumstance of Joseph’s birth is interesting because he was the first-born of his mother, Rachel. She bore him after seven years of disappointing failure to fall pregnant. It was exactly seven years because at that time - at Joseph’s birth - his father Jacob confronted Laban with the fact he had finished seven plus a previous seven years of labour as per their agreement on arriving in Paddan Aram. (Gen 30:25,26)
It was seven more years plus several months before the marriage agreement when Jacob dreamed his dream and built his altar at Bethel. That made it
1928 BC.
So, there were exactly 69 'sevens' (483 years) from Bethel to the Exodus. To summarize:
- 7 years labour for Leah and Rachel
- 7 more years labour for Rachel (Joseph born at end)
- Joseph 30 years old when became Prime Minister
- 7 years abundance started when Joseph appointed
- 2 years into famine when Jacobs family arrived.
- 430 years Israelites lived in Egypt.
- Total years 483 years (69*7)
