Following are a number of back-translations as well as a sample translation for translators of Jeremiah 47:3:

• Kupsabiny: “Those people hear horses running downhill,
  and the chariots of war are making noise,
  and the wheels of the chariots are squeaking
  Parents will forget children there/then
  and (they) will feel weak from fear
  until the hands/arms are lame.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “They will-hear the noise of the galloping of the horses and the noise of the chariots. Fathers will- no-longer -look-back to help their children. Their hands will- just -hang-limp.” (Source: Hiligaynon Back Translation)
• English: “They will hear the sound of the hooves of the enemy horses,
  and they will hear the rumble/noise of the wheels of their enemies’ chariots.
  Men will run away;
  they will not stop to help their children;
  they will be completely weak and helpless.” (Source: Translation for Translators)
