In reply to "Posted by ESC on October 30, 2005" (https://www.phrases.org.uk/bulletin_board/43/messages/952.html) . I am suggesting that the origin of the saying "The long and the short of it" comes from the Bible at Mark 16:8. Some manuscripts follow with either a long or short version. This seems to predate other opinions by several hundreds of years.
