I want to know the answer to the following question:
How common are variations in text that alter the meaning of the Urtext of the Hebrew Bible?
All the background I'm provided with is that "Shemaryahu Talmon, who summarized the amount of consensus and genetic relation to the Urtext of the Hebrew Bible, concluded that major divergences which intrinsically affect the sense are extremely rare.". Is that enough to answer the question?
Answer: yes
