How and when was the Bible divided into chapters and verses?
Stephen Langton, in the 12th century, added what we use today as the chapter divisions. He did this into the Latin Vulgate. The tradition is that these divisions were later transfered to the Hebrew Bible. From manuscripts dating back to the fourth century, however, some form of chapter divisions were used. In 1551, Robert Estienne (a.k.a. Stephanus) added verse divisions to his fourth edition of the Greek New Testament, while en route between Paris and Lyons, France. The first translation to employ his versification was the Geneva translation of 1557 (whole Bible, 1560).
