Besides for the odd letter, such as an extra Vov or Yud, what Scriptual verses that we would find in Tanach today, were once or still debated by Halachic Authorities as to what is the correct text. Or has the text of the Chumash and Nach always been clear as day as to what the exact text is?
To be clear, an entire word must be missing or added to satisfy the above.
For some background why I am asking this question, please see my other question: Did Mesushelach survive the flood according to any sources?
