Can anyone give me the origin of the phrase "what the right hand giveth, the left hand taketh away"?
I had assumed it was a Bible quote, but my Google ninja skills have failed to bring up a chapter and a verse.
Stephen K. Stephenson has published a comprehensive series of videos that show how calculations were done with stones (calculus = little stone). To summarize: to denote the number IV, he places one stone in a space that represents the number 5 on the right side of his abacus and one stone on a line representing the number 1 on the left side, so the I on the left and the V on the right in "IV" make perfect sense. In very concrete terms, the left side of the abacus (and the left hand) "taketh away".
Is it reasonable to say that this expression has an origin in arithmetic manipulations?
