Following are a number of back-translations as well as a sample translation for translators of Isaiah 30:14:

• Kupsabiny: “That wall shall break into pieces like a pot of clay
  that has completely gone to pieces.
  It will be like a pot that has been crushed
  until there is no potsherd left
  that can be used to take fire from the fireplace
  or that can be used to draw some water from a pool.” (Source: Kupsabiny Back Translation)
• Newari: “Like the pot of a potter smashed [and] pulverized,
  they are also about to be broken into pieces,
  then, having been broken into pieces, there will not be even one for taking charcoal from the stove
  from the remaining pieces, or for drawing water from a well."” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) will- be-smashed like a clay-pot, which because of being-smashed completely/totally/severely there is no portion where a live-coal/ember can-be-placed or (that) can-be-used to scoop water.” (Source: Hiligaynon Back Translation)
• English: “You will be smashed like a clay jar is smashed when it is dropped,
  and it shatters completely, with the result that there is not one piece big enough
  to carry some coals from a stove
  or to carry a little bit of water from a well.’” (Source: Translation for Translators)
