Assemble from wherever you’re at,
gather before the Lord and fall flat.
Cease your caterwaul;
The Lord will judge them all
including Jumping Jehosephat!
Jehosephat is one of the “mighty ones” wakened for judgement – thus a ghost. The phrase “jumping Jehosephat” goes back, at least, to the 1865 novel Paul Peabody by Percy Bolingbroke St. John where it is: "By the shaking, jumping ghost of Jehosaphat!”
