Following are a number of back-translations as well as a sample translation for translators of Isaiah 4:24:

• English: “Therefore, just like fires burn up stubble
  and dry grass shrivels up and quickly burns in flames,
  it will be as though those people have roots that will rot
  and have flowers that will wither.
  That will happen because they rejected the laws of the Commander of the armies of angels;
  they have despised the messages of the Holy One of Israel.” (Source: Translation for Translators)
