Following are a number of back-translations as well as a sample translation for translators of Lamentations 1:15:

• Kupsabiny: “God turned his back on
  all my warriors whom I had put my hopes on.
  Enemies raided and came to smash my soldiers.
  God smashed them
  like grapes are squashed,
  where they are being pressed.” (Source: Kupsabiny Back Translation)
• Newari: “‘The Lord has treated with contempt
  all strongest warriors who defended me.
  He has sent soldiers to destroy
  my young men.
  The Lord trampled me, the virgin daughter of Judah,
  in his winepress like grapes.” (Source: Newari Back Translation)
• Hiligaynon: “The Lord rejected all my soldiers. He gathered soldiers to destroy my young men. The residents of Juda (are) as-if-like just grapes which were-trampled by the Lord.” (Source: Hiligaynon Back Translation)
• English: “Yahweh looked at our mighty soldiers
  and laughed at them.
  He has summoned a great army
  to come and crush our young soldiers.
  It is as though Yahweh has trampled on us people of Judah
  like people trample on grapes in a pit to make wine.” (Source: Translation for Translators)
