Following are a number of back-translations as well as a sample translation for translators of Jeremiah 46:22:

• Kupsabiny: “Egypt will scream like a snake that is fleeing
  because the enemies have come close.
  Those people come with axes
  like people who are cutting down trees.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Those from-Egipto will-flee like a snake that hisses while the enemies are-attacking. They will-attack them with axes like people who are-cutting-down trees.” (Source: Hiligaynon Back Translation)
• English: “The soldiers of Egypt will run away,
  as silently as a snake scurries/crawls away.
  The army of the enemy will advance;
  they will march along carrying their axes
  like men who cut down trees.” (Source: Translation for Translators)
