Following are a number of back-translations as well as a sample translation for translators of Jeremiah 31:37:

• Kupsabiny: “If it was possible for the world above to be measured, and it be known/understood how the world below supports (it), then that is the time when I shall turn my back to the people of Israel on account of all those words/deeds they have done. It is I God who has spoken.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Just as heaven cannot be measured and the foundation of the earth cannot be fathomed, I cannot reject all the descendants of Israel because of the sins they have-done. I, the LORD, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)
• English: “And this is what I say:
  ‘No one can measure the sky,
  and no one can find out what is supporting the earth.
  Similarly, I cannot reject forever the descendants of Jacob
  because of all the evil things that they have done.’
  That is certain, because I, Yahweh, have said it!” (Source: Translation for Translators)
