How Are We to Explain the Scribal Errors in the Hebrew Manuscripts?

We know that there are mistakes in the Hebrew Old Testament manuscripts because they all have some different readings in them. If there were no mistakes, all of the Hebrew Old Testament Manuscripts would have read exactly the same with absolutely no difference, which would have required that God repeat the miracles of inspiration, moving the copyists along with Holy Spirit like he had done with the authors every time they picked up a pen. Yet, this simply was not the case. Mistakes were made. In fact, the same sopherim in Jesus’ day took liberties with the text. Were these so serious that our Bible was corrupted so that the meaning God wished to convey was lost?
