Following are a number of back-translations as well as a sample translation for translators of Joel 2:7:

• Kupsabiny: “They run like (young) men of war,
  climb the wall like soldiers.
  They march with pride
  and do not stray aside when they come.” (Source: Kupsabiny Back Translation)
• Newari: “They attack like mighty warriors.
  And they climb walls like soldiers do.
  They walk in proper order
  and they don’t break the line.” (Source: Newari Back Translation)
• Hiligaynon: “They attack and climb-up/go-up the stone-walls like soldiers. They walk straight-ahead and do- not -turn-to-one-side-or-the-other on their path. They do- not -jostle-each-other; and even-if they encounter weapons-of-war they do- not -scatter.” (Source: Hiligaynon Back Translation)
