By “original Bible” do you mean the Masoretic text, which is in the Hebrew language and finalized in about the year 1100 A.D.? Or the Septuagint text, the Greek translation of the Torah dating around 300 B.C.? Or some other “Bible” from some point across that 1,400 year stretch?
You don’t know. Or you say “faith” and put the contradictions out of your mind.
