Footnote
In chapters 23-37 various commentators have made many guesses that this or that part did not originally belong to the book of Job or that some verses originally belonged in a different part of Job’s speech or in Bildad’s speech or in a third speech of Sophar’s. The guesses that have been made by the largest number are that chapter 28 did not belong to the book and that chapters 32-37 did not belong to it.
