isaiah 25:10 For in this mountain shall the hand of the LORD rest, and Moab shall be trodden down under him, even as straw is trodden down for the dunghill. - Free Bible Online

      10. rest--as its permanent protector; on "hand" in this sense; compare Ezr 7:6, 28.
      Moab--while Israel is being protected, the foe is destroyed; Moab is the representative of all the foes of God's people.
      under him--Rather, "in his own place" or "country" (Ex 10:23; 16:29).
      for the dunghill--Rather, "in the water of the dung heap," in which straw was trodden to make it manure (Ps 83:10). HORSLEY translates either, "in the waters of Madmenah," namely, for the making of bricks; or as the Septuagint, "as the threshing-floor is trampled by the corn-drag" (see Margin; Mic 4:11-13).
