Nelson Mandela just passed away today. Many of my friends are writing tributes on their Facebook pages. One goes like this:
I typically have an aversion to joining the masses on these matters, but far be it from me not to add to honouring of such a history-making, extraordinary man. If anyone deserves peaceful rest, it's you, Mr. Mandela. A job well done.
I've never seen such sentence structure as far be it from me.... Can someone please help me analyse it?
