Following are a number of back-translations as well as a sample translation for translators of Amos 5:8:

• Kupsabiny: “It is God who made all the stars
  those that are called Pleiades and Orion.
  He changes darkness to become light
  and he changes the day to become night.
  He gathers the water of the ocean
  and makes it rain on the land.
  He is God.” (Source: Kupsabiny Back Translation)
• Newari: “He who created groups of stars such as the Pleiades and the Orion,
  he who turns deep darkness into morning light and
  makes the day into dark night,
  that God summons the waters and they gather,
  and then He pours them out
  His name is the LORD.” (Source: Newari Back Translation)
• Hiligaynon: “God is the one-who-created the groups of stars which-are-called Pleyades and Orion. He (is) the one-who-changes the darkness into light, and the day into night. He (is) the one-who-gathers the water of the sea to the clouds and he causes- it -to-rain upon the ground. His name is the LORD.” (Source: Hiligaynon Back Translation)
• English: “Do you know who created all the groups of stars
  and put them in their places?
  Each morning he causes the darkness to become the dawn,
  and each evening he causes the daylight to become darkness.
  He scoops up water from the oceans to become clouds,
  and then he dumps the water from the clouds onto the earth.
  The one who does those things is named Yahweh.” (Source: Translation for Translators)
