The Book of Job is quite possibly the strangest book in the Hebrew Bible, and is notoriously difficult to date.
In essence, Job is an essay on the problem of evil. The book starts with God and Satan discussing Job, a “perfect and upright” man who “feared God and eschewed evil” (1:1). Satan tells God that Job is only virtuous because he is well off; were he to suffer, he would surely “curse thee to thy face” (1:11). God accepts the challenge and gives Satan permission to destroy Job’s life.
Since the story lacks any historical context and no historic individuals are mentioned, it is very hard to date.
There's a snag, though. The language in Job is unlike any other found in the Bible, or outside it. True, the book is written in Hebrew, but it is very strange Hebrew indeed. It has more unique words than any other book of the Hebrew Bible. The language is archaic, which would indicate that it was very ancient: but it is also heavily influenced by Aramaic, which would make it relatively late.Read more: Haaretz News
