Following are a number of back-translations as well as a sample translation for translators of Malachi 2:17:

• Kupsabiny: “God is fed up with your words/matters. But you are asking, ‘How has God become fed up?’ He gets fed up when you say, ‘All people who do sin are good and God is happy with those people.’ And you also ask, ‘Where is this God who should do what is right/true/justice?’” (Source: Kupsabiny Back Translation)
• Newari: “You have made the LORD tired with your words.
  and still you say, "how have we made him tired?"
  By your saying, "Everyone who does evil is good in the eyes of the LORD, and he has delight in them," or "Where is God who is supposed to be just?"” (Source: Newari Back Translation)
• Hiligaynon: “Malakias still said to the Israelinhon, ‘You (plur.) have-caused- the LORD -to-be-disgusted with what you (plur.) speak/say. But you (plur.) still ask, ‘Why, what (are) we (excl.) saying that makes- him -disgusted?’ You (plur.) are-saying that all who do evil/bad (are) good in the sight of the LORD and he (is) happy with them. You (plur.) even ridicule saying, ‘Where (is) now the God who will- judge?’ ’” (Source: Hiligaynon Back Translation)
• Kankanaey: “God is already tired-of your words. You ask the reason for it, but the reason is your saying that all who are-doing what is evil are good in the viewpoint of God and you say that he is pleased with them. Likewise also your saying, ‘Where is the one they say is a just/righteous God.’” (Source: Kankanaey Back Translation)
• English: “Yahweh also says, ‘What you have said has caused me to become disgusted.’
  You reply, ‘What have we said that caused him to become disgusted?’
  The answer is that you have caused him to become disgusted by saying that Yahweh is pleased with all those who do evil things. You have caused him to become disgusted by constantly asking, ‘Why does God not act fairly?’” (Source: Translation for Translators)
