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?
For easy indexing. Lots of influential literary works have this. There's a universal standard indexing for both the works of Plato and Shakespeare, for example.
