Following are a number of back-translations as well as a sample translation for translators of Isaiah 10:13:

• Kupsabiny: “The king of Assyria is boasting,
  ‘I defeated (them) in my own power alone,
  I fought with wisdom.
  I broke through the borders of nations,
  and robbed the things in their treasuries.
  I removed like a bull of fighting,
  the kings of those countries.” (Source: Kupsabiny Back Translation)
• Newari: “For he says,
  "’This has been done by the strength of my hand
  and by my wisdom, for I have insight.
  I have removed the boundaries of land after land.
  and I have plundered their treasuries.
  A very strong person like me has crushed their king.” (Source: Newari Back Translation)
• Hiligaynon: “For he says, ‘I have-done this because of my strength and wisdom: I took-by-force the many nations, and their wealth. I am like a bull; I defeated their kings.” (Source: Hiligaynon Back Translation)
