Following are a number of back-translations as well as a sample translation for translators of Joel 1:7:

• Kupsabiny: “That swarm of locusts ate our vine plants
  and they chewed up our fig trees.
  Trees were debarked
  the branches were left bare and without bark.” (Source: Kupsabiny Back Translation)
• Newari: “They destroyed my grape vines,
  then ruined my fig trees.
  They stripped off the bark of the fig trees and threw it away
  and left the branches of the grape vines white.” (Source: Newari Back Translation)
• Hiligaynon: “They have-destroyed the grape vines/[lit. plants] of the LORD and his fig trees. They gnaw its bark/[lit. skins] until the branches become-white.” (Source: Hiligaynon Back Translation)
• Kankanaey: “They have destroyed all-at-one-time our grape plants. They have also gradually-eaten-away our fig (loan igos) trees. They have broken-off their twigs and peeled-them (of their bark) and they have already become-white.” (Source: Kankanaey Back Translation)
