Following are a number of back-translations as well as a sample translation for translators of Jeremiah 47:7:

• Kupsabiny: “But then how can the sword take a break
  and (yet) God has given (it) work?
  God said that (it) should go and fight against Ashkelon
  and the people who live at the shore of the ocean.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “But how will- it -stop for I command it to attack Ashkelon and the people who live near the seashore?’” (Source: Hiligaynon Back Translation)
• English: “But it would not be right for their swords to stay there,
  because Yahweh has commanded their enemies to do something more;
  Yahweh intends to tell them to attack all the people living in Ashkelon and in other cities along the coast.” (Source: Translation for Translators)
