Following are a number of back-translations as well as a sample translation for translators of Isaiah 10:15:

• Kupsabiny: “Does an axe exalt itself to be
  fierce more that the person who uses it to split firewood?
  Or is the saw above the person who cuts with it?
  A walking stick cannot rise above the person who holds it,
  and a whip cannot carry the person who carries it.” (Source: Kupsabiny Back Translation)
• Newari: “Can the axe raise itself above who use it?
  Can the saw raise itself above who use it?
  As if a stick itself uses a man who uses it
  Or a wooden hammer itself lifts the one who is not wood.” (Source: Newari Back Translation)
• Hiligaynon: “Is the ax or the saw above than the one-who-uses it? Is the something-to-hit can-lift-up the one-who-holds it?” (Source: Hiligaynon Back Translation)
