I am not entirely sure what your question means, but here goes.

The Old Testament (aka the Hebrew Bible) is a collection of ancient writings spanning hundreds of years, primarily focused on the (alleged) history of the Hebrew people and the nation of Israel.

The New Testament is a collection of writings from primarily the first and second centuries CE, focused on the (alleged) life and teachings of Jesus, his death and resurrection, and the establishment of the Christian church.

In both cases, my understanding of the scholarly literature (I am not a biblical scholar I just listen to a few on social media) is that they were written by humans for a variety of purposes, then edited and curated over time to try to establish authority and accrue the power that comes with that authority. No scripture as far as we can tell was ever divinely inspired, let alone handed down from a divine being itself.

The King James Bible is just a translation of the Christian biblical canon, largely based on a prior English translation. I’ll be honest I have forgotten the purpose behind its creation, and I do not care enough to go find out.

Hopefully this was helpful?
