Following are a number of back-translations as well as a sample translation for translators of 2 Samuel 23:7:

• Kupsabiny: “If/When they are taken/held/touched, one uses (a) metal or a spear,
  and (they) will be burnt completely where (they) are.” (Source: Kupsabiny Back Translation)
• Newari: “One must use iron tools or a spear.
  Where thorn plants are gathered, there they must be burned.” (Source: Newari Back Translation)
• Hiligaynon: “But the wicked people are like thorny bushes that are being-thrown-away.
  They could- not -be-taken-away by just bare-hands but-rather had to use as-well tools [linker]/of iron and wood,
  and they will-be-burned in the place where they are-piled-up-at.’” (Source: Hiligaynon Back Translation)
• English: “Someone who wants to get rid of thornbushes does not grab them;
  he uses an iron shovel or a spear to dig them out
  and then he burns them completely.” (Source: Translation for Translators)
