Block Cipher Explanation

I was wondering if the community can help explain a concept for me since the Official CISSP CBK book and Shon Harris AIO is confusing the heck out of me. I tried looking it up online (Wikipedia, etc...) and that was more confusing.

Page 692 on Shon Harris AIO
Page 347 on Official CISSP CBK

Anyone have a relatively simple to understand explanation of Block Ciphers and the S-box? More specifically when the Substitute Bytes happens.
