Title:
Textual_criticism

Context:
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. As far as the Hebrew Bible referenced by Old Testament is concerned, almost all of the textual variants are fairly insignificant and hardly affect any doctrine. Professor Douglas Stuart states: "It is fair to say that the verses, chapters, and books of the Bible would read largely the same, and would leave the same impression with the reader, even if one adopted virtually every possible alternative reading to those now serving as the basis for current English translations."

Question:
How common are variations in text that alter the meaning of the Urtext of the Hebrew Bible?

extremely rare
