Following are a number of back-translations as well as a sample translation for translators of Isaiah 16:9:

• Kupsabiny: “But now, I am crying over the people of Jazer
  because of the grapes/vines of Sibmah.
  Tears are flowing because of you (plur.), oh, people of Heshbon and Elealeh.
  because there is no crop/food which people can pluck so as to be happy.” (Source: Kupsabiny Back Translation)
• Newari: “So for the grapevines of Sibmah I will weep
  like I will weep for [the grapevines of Jazer.
  O Heshbon, O Elealeh,
  I will drench you with my tears.
  You have become ripe fruit
  and no sound of the joy of harvest has come.” (Source: Newari Back Translation)
• Hiligaynon: “Therefore I (am) crying, as those of/from-Jazer are-crying, because of the fields of grape/(vineyards) of Sibma. I cry for Heshbon and Eleale for the shouts of joy over their produce can- no-longer -be-heard.” (Source: Hiligaynon Back Translation)
• English: “So I will weep for Jazer
  and for the grapevines of Sibmah.
  I will shed tears for all of you.
  I will cry because people will no longer shout joyfully, like they usually do
  when they gather the fruit that ripens in the summer/hot season and the other crops that they harvest.” (Source: Translation for Translators)
