Does your printer software include a Booklet printing option. That said it can be quite a longwinded proceedure to print more than just a few copies. I would consider a commercial printer if you want a lot of them. You can provide the copy yourself of course.
Add numbers to existing text
Put your cursor at the start of each paragraph/verse in turn and press the 'Numbering Icon' in the toolbar this will insert consecutive numbers at the beginning of the Paragraph/verse. You need to have the Formatting toolbar activated (right click & tick on)
