Following are a number of back-translations as well as a sample translation for translators of Ezekiel 31:8:

• Kupsabiny: “The cedars in the field/garden of God were not able to compare with this one nor was its branches like those of the cypress/fir tree or like (those) of a tree called plane tree/coomnyaanteet. There was no single tree among those in the garden/field of God that could be compared to it.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Even the cedar trees in the garden of God can- not -be-compared to the beauty of this tree. Even the abeto/fir trees and plane tress can- not -compare to the beauty of its branches. No tree ever in the garden of God can-be-equaled/[lit. level] to the beauty of this tree.” (Source: Hiligaynon Back Translation)
• English: “The cedar trees in my garden in Eden were not as great as that tree,
  and the branches of the pine/cypress trees were not as long and thick as the branches of that cedar tree.
  And the branches of the plane trees were not as long and thick, either.
  No tree in my garden was as beautiful as that cedar tree.” (Source: Translation for Translators)
