I don't have a paper copy of Harper's Bible Commentary so I don't know if I'm missing something or not but it seems odd that almost 30 verses wouldn't be commented on.

Is this a typo? Or is there another way of reporting a missing section of a book (if it indeed is a missing section--which I'm hoping someone with Harper's Bible Commentary can confirm or rule out)?
Thanks for your help.
Peace & Blessings,
