Following are a number of back-translations as well as a sample translation for translators of Hosea 9:12:

• Kupsabiny: “Even if they rear children,
  I shall kill them all!
  How bad it will be for those people
  if/when I turn my back on them!” (Source: Kupsabiny Back Translation)
• Newari: “Even if they give birth to a child and it grows up,
  I will take that child,
  Alas! What sorrow for them
  when I turn away from them.” (Source: Newari Back Translation)
• Hiligaynon: “Even if they can-give-birth, I will-take-away all their children and you (plur.) will-mourn. You (plur.) are very pitiful when I leave you (plur.) now.” (Source: Hiligaynon Back Translation)
• English: “Even if their children are born and start to grow up,
  I will cause all of them to die while they are still young.
  Terrible things will happen to them
  when I abandon them!” (Source: Translation for Translators)
