Not a Bible or religion bashing thread!
I saw a post on fb about someone who'd actually read their bible, and realised there were more than x2 of some animals loaded onto the ark, and their mind being blown by that.
I've been googling and there seem to be loads, it makes me want to actually whip out a Bible and start reading it properly.
Some of the top of my head, I already knew about are
Hell.
The true nature of angels, and what they really look like.
Who wrote the Torah, the Gospels and various other books.
That the Lords prayer was supposed to be copied, and not just read as an example.
Mary Magdalene being a prostitute.
How Esther became a Queen.
David and Jonathan being "friends"
There are bound to be tons more.
