Following are a number of back-translations as well as a sample translation for translators of Jeremiah 10:9:

• Kupsabiny: “(People) bring flat (hammered) and amazing silver from Tarshish
  and gold from Ophir.
  When skilled craftsmen have covered (them)
  they dress (them) in red and purple clothes
  that sewers that are skilled in sewing sew.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “They have-had- the carpenters and silversmith -made little-gods/false-gods coated with silver from Tarshish and gold from Ufaz. Then they clothed them with blue and purple cloth sewed by expert tailors.” (Source: Hiligaynon Back Translation)
