Following are a number of back-translations as well as a sample translation for translators of Isaiah 19:14:

• Kupsabiny: “God has made those people confused,
  and led the people of Egypt astray in their thoughts.
  So, the land of Egypt is staggering.
  (They) are like a drunkard
  who is sliding/slipping in his vomit.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD has given them a spirit of confusion.
  Like a drunkard staggering in the place where he had vomited,
  by the work they have done to their own people in the land of Egypt,
  they have caused confusion.” (Source: Newari Back Translation)
• Hiligaynon: “As-if the LORD is-causing-to-become-dizzy the head of those of/from-Egipto. They are wayward in all they do. They are like a drunkard that stagger and vomits.” (Source: Hiligaynon Back Translation)
• English: “Yahweh has caused them to be very foolish,
  with the result that in everything that they do, it is as though the people of Egypt stagger
  like a drunken person staggers and slips in his own vomit.” (Source: Translation for Translators)
