Following are a number of back-translations as well as a sample translation for translators of Obadiah 1:18:

• Kupsabiny: “The house of Jacob will become fire and that of Joseph will become a flame. They will destroy the house of Esau like when fire destroys maize stalks that are dried up. No descendant of Esau will return (home). It is I God who has said (this).” (Source: Kupsabiny Back Translation)
• Newari: “The descendants of Jacob and Joseph will be like a blazing fire,
  the descendants of Esau will be like stubble.
  And they will be put into it and burnt up.
  Not one of Esau’s descendants will survive.’
  The LORD himself has spoken.” (Source: Newari Back Translation)
• Hiligaynon: “The descendants of Jacob and of Jose will-be like fire that will-destroy the descendants of Esau, like the burning of the straw. And no one will-be-left among the descendants of Esau. This will- surely -happen, for I, the LORD, (am) the-(one) saying this.” (Source: Hiligaynon Back Translation)
• English: “The descendants of Jacob and his son Joseph will be like a fire,
  and the people of Edom will be like stubble that will be completely burned in that fire.
  Not one person will remain alive.
  That will surely happen because I, Yahweh, have said it.’” (Source: Translation for Translators)
