Some of the “First” and “Second” books were divided after they were written
If the books of 1 and 2 Kings were combined, they would be the longest book of the Bible. I bring that up because 1 & 2 Kings were originally written as one book. The same goes for 1 & 2 Samuel and 1 & 2 Chronicles.
Why did these books get split? Because in the old days, they could
n’t print massive tomes for each book of the Bible. It was hard to fit the very lengthy works on one scroll—and even if the scroll was big enough for all that content, it would be too heavy to manage. So they broke some of the longer books down into two volumes. So the book of 2 Samuel is really more like the book of Samuel, part two.
The Bible was written by people from diverse occupational backgrounds
But other parts of the Bible are written by farmers, fishermen, a tentmaker, homeless prophets, a doctor, a professional scribe, vocational musicians, pastors, etc.
We have Early and latter PROPHETS :
Four Early Prophets- Joshua, Judges, Samuel, Kings
Five Latter Prophets- Isaiah, Jeremiah, Ezekiel, The Twelve
There are 21 dreams recorded in the Bible
And most of them are had by two different men named Joseph! You can see the whole list here.
The Bible was written in three languages
Those languages are Hebrew, Aramaic, and Greek. Most of our Old Testament was written in Hebrew, which was the language the original readers spoke. A few bits of the Old Testament were written Aramaic (looking at you, Ezra and Daniel). The New Testament was written in Greek, the commonly-spoken language of the time.
