Following are a number of back-translations as well as a sample translation for translators of Isaiah 10:26:

• Kupsabiny: “The God of power himself will beat those people with his stick like when he beat the Midianites at the rock of Oreb. He will punish the Assyrians like when the Egyptians were punished.” (Source: Kupsabiny Back Translation)
• Newari: “Like the LORD Almighty
  near the big rock of Oreb, struck down the Midianites
  he is about to strike them with a whip.
  And like in the land of Egypt he raised the sea with his stick.” (Source: Newari Back Translation)
• Hiligaynon: “I will-punish them like what I did to those of/from-Median there at the Rock of Oreb and to those who-came-from Egipto when I drowned them in the sea.” (Source: Hiligaynon Back Translation)
