The traditional scholarly consensus is that Job is the oldest book in the Bible, with a date of origin in the Bronze Age, around 1500 BCE, but recently I noticed a few problems with this, which I will explain below.
If the King James Version translation of Job 20:24 is correct, then the references to “iron” and “steel” in that verse rule out a date of origination in the Bronze Age, for iron and steel were utterly unknown to Bronze Age peoples, for obvious reasons of course.
Therefore, the date when Job was written should be placed in the Iron Age, rather than the Bronze Age, in line with the other books of the Bible. So if I`m correct, the view that Job is an outlier is wrong, and needs to be corrected in light of Job 20:24.
I should note that I’ve received some criticism over my dating of the Book of Job, with some commentators noting that the oral traditions that the Bible is ultimately based upon are most likely far older than the works of the Bible themselves, and while I acknowledge that as likely as well, I should mention that my dating only takes place to when the oral traditions of Job and the other books of the Bible were put to writing, not when the oral traditions they are based upon first came into being.
The entirety of the verse of Job 20:24 is placed below:
He shall flee from the iron weapon, and the bow of steel shall strike him through.
