Following are a number of back-translations of Romans 8:20:

• Uma: «For long ago, this world and all its contents became cursed, with the result that their lives were no longer useful [i.e., no longer fulfilling their purpose]. That happened not because of the desire of this world. God himself cursed this world, for thus was his decision.» (Source: Uma Back Translation)
• Yakan: «All that God has created, is not now as (it was) at the beginning. But it is not from their fault/wrong that they are not good as at the beginning, but it is from the will/want of God. But these created things of God» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «For all creation, because it was what God wanted, God made it long ago so that it’s true purpose might be removed. However, we are expecting a time in the future,» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «Because God condemned his creation so that their proper purpose/function would not be fulfilled. They of course were not the ones who planned to undergo such a punishment, but rather it was God’s plan. But there was nevertheless something to hope-for,» (Source: Kankanaey Back Translation)
• Tenango Otomi: «Because God made the world but it was spoiled when God said there would be the punishment on account of sin committed by Adam. But also God determined that there would come the day that the earth would become new.» (Source: Tenango Otomi Back Translation)
