Hi. After doing some research, I have found that many ( if not, most) scholars believe that Job was written by 2 authors, because the book of Job also talks about the exile, and there are some writings of the book that most likely are before the exile. As you said, a lot of the books genre seems to be wisdom reading, like proverbs. Proverbs was written by Solomon (Ecclesiastes 12:9). Additionally, the Hebrew title is translated proverbs of Solomon. Ecclesiastes is also wisdom reading, and there are verses that indicate Solomon was the author. Because all the books listed were written by Solomon, it’s most likely that the pre-exile part of the book was written by Solomon. However, someone on the internet said this: “1. Archaic spelling. If there is a difference in spelling a word, Job consistently uses the oldest form. For example, “yom” may be spelled with a waw or without. With is the oldest spelling, and that’s how it’s spelled in Job." As you can see, this person is saying that the book of Job uses archaic spelling, and because it uses old-fashioned spelling, it must be old. However, as I said above, it seems likely that Solomon was the author for the pre-exilic part of the book. According to this person, Job is the only book that uses archaic spelling. However, even most scholars agree that Solomon is one of the most likely candidates for authorship. If, according to this person, Job is the only book that uses archaic Hebrew, and all the other books didn’t use it, why aren’t Proverbs and Ecclesiastes written that way? Or are they? Is this person correct? Do other books in the Bible use archaic Hebrew?
