Following are a number of back-translations as well as a sample translation for translators of Isaiah 30:3:

• Kupsabiny: “So, they shall have nothing to say (be speechless)
  because they trust in the powers of Pharao
  and they are lost in their thinking (confused)
  because they trust in that land of Egypt.” (Source: Kupsabiny Back Translation)
• Newari: “But you will fall into shame because of Pharaoh’s protection,
  then taking refuge in the land of Egypt, you will become disgraced.” (Source: Newari Back Translation)
• Hiligaynon: “But they will- only -be-put-to- shame for asking protection from the king of Egipto.” (Source: Hiligaynon Back Translation)
