There is no "Biblical route" because the Bible is internally inconsistent.

It is no wonder that it is internally inconsistent, because the Bible is a very large collection of texts that were written and edited and re-edited over a long period of time by multiple contributors who were largely anonymous, in multiple languages. That alone makes it impossible for something like that to be internally consistent.

Then there is the issue of multiple translations that may give the same passages of text different meanings.

Therefore, the quest for "the Biblical route" is doomed from the start and futile.
