Exodus chapter 6 part 3

*In the clan section we see that:

-Each of Moses's direct ancestors supposedly lived well past 100 years

-Moses and Aaron were from the tribe of Levi. Their mother was their paternal grandfather's sister, therefore also from the tribe of Levi. Levi was the father of Kohath, Moses's grandfather, and Jochebed, Moses's mother. Kohath was the father of Amram, Moses's father. In other words, Moses's father married his own aunt.

-Aaron's wife Elisheba was the daughter of Aminidab and the sister of Nashon. This is very interesting because, if we look ahead to the book of Ruth 4:18-22, which supposedly would have been written hundreds of years later, we see that Aminidab was the great grandson of Perez, the son of Judah by Tamar back in Genesis chapter 38. Nashon was supposedly the great, great, great grandfather of David. The text is anticipating David, surely not a coincidence.

-In 400 years of captivity, there were only four or five generations born, from the children of Jacob to the children of Moses and Aaron.

-My study bible's footnotes say that the ages and generations don't quite work in real time, so there must be an explanation for the discrepancy. Maybe the text doesn't mean what it says and the word father needs to be interpreted loosely. Maybe it really means "ancestor." Except that doesn't quite work either.
