It always looked so weird to me, like, who not just read the Bible like a proper book instead of having all of those numbering?
I guess it’s because it makes easy to find some specific line? But that is from an academic perspective instead of something you would put in a faith book?
When did that started and why they put all the numbering?
You don't need to write it like this. Just write normally (prose or poetry, your choice), and other people will fragment your text this way, while either discussing it [proto-]academically or looking for hidden stuff in it.
