Following are a number of back-translations as well as a sample translation for translators of Psalm 77:17:

• Chichewa Contempary Chichewa translation, 2002/2016:
  “The clouds poured their waters down,
  in the sky thunders were heard;
  your arrows flew there and there.” (Source: Mawu a Mulungu mu Chichewa Chalero Back Translation)

  In the heavens it also thundered
  Lightning flashed from all sides.” (Source: Newari Back Translation)

  your arrows fly in all directions.” (Source: Philip Noss in The Bible Translator 1976, p. 100ff. . Noss explains: [For the translation of this verse, the Gbaya translators chose] “grammatical constructions [that] are specifically literary, occurring only in narrative discourse. This pattern was used sparingly, but [here] it seemed appropriate.”

  “Mvua ikamwagika kutoka katika mawingu,
  radi ikanguruma mbinguni,
  vimulimuli vikamulika kotekote.” (Source: Nyakyusa Back Translation)
