@IsaacMoses It seems the history is a bit more nuanced than is typically assumed.
books.google.com/… Chapter divisions came first, but not verse divisions. The non-Jewish world got the verse divisions from a Rabbi Mordechai Natan in the 15th/16th century. Not clear what Rabbi Natan did with chapters, if anything, but I suspect the variance starts in this period. Impossible to say without actually seeing the prints referenced.
