Two expressions more signifying the same thing. The first is used by the prophet, to signify the change God would make in the state of the Edomites, Isaiah 34:4, as will appear by comparing what that prophet saith, with what Jeremiah, Ezekiel, and Obadiah say, upon the same argument, Jeremiah 49:7-22 Ezekiel 35:1-15. And every mountain and island were moved out of their places; all sorts of people shall be destroyed, or all the paganish religion shall be rooted out.
