Q: Who decided that the English Bible should have been divided into chapters and verses?
A: To answer your question, no one really made the decision to divide the Bible into chapters and verses, insofar as anyone in particular. This basically became a necessity as people began quoting from it and had to provide a specific source. Both among Jews and Christians, they began dividing the Bible into chapters and verses. By and large, they were divided mostly along the same lines. Now and then the Hebrew text disagrees with the verse and chapter divisions from the Christian Bible, but that is not very frequent.
