Is it any wonder the human author, Moses, was educated in Egypt? As the story goes in Genesis Joseph was used to organize the prosperity of 7 years to later funnel all the ANE wealth to Egypt and make it the dominant country during that period of history. Later after 40 years of becoming a somebody Moses got to spend 40 years learning to be a nobody to round out his schooling with practical life experience. So we have a guy with literally the best education in the known world with the humility of one pardoned of murder leading God's people to salvation and codifying their history and culture. It's a good story.
