I received the following question:

In Genesis 11:1 it says the whole earth had one language, yet in chapter 10 it says how they were divided according to their languages. Is this another thing like Genesis 1 and 2 where the first chapter is overview and second chapter is detailed?

Yes, Genesis 10 declares an overview of what happened, whereas Genesis 11 goes back and explains it in more detail.

I am not sure that Genesis 2 is entirely just a more detailed repetition of chapter 1. It does offer more detail about the creation of Adam on day 6. I don’t think much else is a repeat, however.
