Books of the Hebrew Bible were scrolls, wrapped round rollers (Jer. 36: 2) and unrolled for the appropriate place (Luke 4: 17). Two hands were therefore required for reading them. The Christians' bibles by the 2nd cent. CE were in the form of papyrus codices with pages fastened on the spine. These were not only more convenient than rolls but also served to point the difference from practice in the synagogues.
