Following are a number of back-translations as well as a sample translation for translators of Isaiah 24:7:

• Kupsabiny: “The vines will wither
  and wine will be scarce.
  Everyone who was happy will walk away sad.” (Source: Kupsabiny Back Translation)
• Newari: “The grapevines are shriveling up
  and the new wine is running low [lit.: subsiding].
  Those who celebrated with joy at one time
  now express sorrow.” (Source: Newari Back Translation)
• Hiligaynon: “The grapes will-wither, and wine will-be-finished. The ones-(who)-are-rejoicing will-mourn,” (Source: Hiligaynon Back Translation)
