Following are a number of back-translations as well as a sample translation for translators of Amos 8:8:

• Kupsabiny: “So, I will make the earth shake so that all people can feel the consequences. The whole world/earth will tremble, the world/land/earth will move quickly and sink like the river Nile.” (Source: Kupsabiny Back Translation)
• Newari: “Does not the earth tremble because of it?
  Do not all who live in it lament?
  The earth will rise like the Nile River at flood time;
  it will heave up,
  then fall down again. ” (Source: Newari Back Translation)
• Hiligaynon: “Because of this I will-cause- your (plur.) land -to-shake and you (plur.) will-cry/weep. Your (plur.) land will-shake very much, as-if like the high-tide and low-tide of the Nile River in Egipto.” (Source: Hiligaynon Back Translation)
• English: “Because of those evil things, your country will certainly soon be shaken,
  and all of you will mourn.
  It will be as though it will repeatedly rise and fall
  like the Nile River that gets full of water and overflows it banks
  and then settles back into its riverbed.” (Source: Translation for Translators)
