Following are a number of back-translations as well as a sample translation for translators of Amos 2:6:

• Kupsabiny: “God is saying,
  ‘The people of Israel sinned repeatedly.
  I will punish those people for sure
  because they sold off righteous people to become slaves
  when they were unable to pay their debts.
  The poor were given out (sold) to release/redeem shoes.” (Source: Kupsabiny Back Translation)
• Newari: “This is what the Lord’s says,
  "The people of Israel have sinned again and again,
  I will surely punish them.
  They sold righteous for silver
  and the poor for one pair of sandals” (Source: Newari Back Translation)
• Hiligaynon: “This is what- the LORD -says concerning Israel: ‘Because of the continuous sinning of those who-come-from-Israel, I will- surely/severely -punish them. For they sold as slaves the people who (have) no sin, just because of their loans. They do this to the poor-ones even-though their loan is just a pair of sandals.” (Source: Hiligaynon Back Translation)
• English: “Yahweh also said this:
  ‘I will punish the people of Israel because of the many sins that they have committed;
  I will not change my mind about punishing them,
  because they sell righteous people to get a small amount of silver;
  they sell poor people, causing them to become slaves,
  getting for each of them only the amount of money with which they could buy a pair of sandals.” (Source: Translation for Translators)
