Following are a number of back-translations as well as a sample translation for translators of Isaiah 34:6:

• Kupsabiny: “Blood shall be dripping from the sword of God
  and have fat.
  (it) has the blood of sheep and goats
  and fat from the kidneys of rams.
  God shall make sacrifices in the city if Bozrah and Edom,
  and much/many shall be killed in the land of Edom.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD’s sword is drenched in blood.
  and [it] is full of fat.
  it has been drenched in the blood of lambs and female goats, and fat of the kidneys of the rams.
  for the LORD will offer this sacrifice in the city of Bozrah.
  Then he will slaughter many in the area of Edom.” (Source: Newari Back Translation)
• Hiligaynon: “The sword of the LORD will-be-soaked/covered with blood and fat, as-if (it) had-been-used to slaughter the goat and sheep offerings. This is because the LORD will-kill the people of Bozra as an offering. He will-kill many in the other towns of Edom.” (Source: Hiligaynon Back Translation)
