Following are a number of back-translations as well as a sample translation for translators of Nahum 1:3:

• Kupsabiny: “He does not become angry quickly and he has power. He punishes sinners. A whirlwind rises where God is walking, and clouds are like dust of/from his feet.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD is slow to feel anger, he is very strong.
  The LORD will never let the guilty go without punishment.
  The storm and the whirlwind are his path.
  And as for the clouds, they are dust under his feet.” (Source: Newari Back Translation)
• Hiligaynon: “(It is) true he does- not -easily/quickly get-angry, but he is very mighty and he will- surely -punish the one-who-has-sinned. When he passes by the wind howls-strongly and it-storms. The clouds are-like dust that fly-off at his feet.” (Source: Hiligaynon Back Translation)
