Following are a number of back-translations of Romans 3:20:

• Uma: “There is not one who is upright in God’s sight from their following of the Lord’s Law. For it is from the Lord’s Law that we come to know that we have sinned.” (Source: Uma Back Translation)
• Yakan: “For there is really no person forgiven and considered/regarded straight by God because of his following the law of God but because of the law of God hep do we (incl.) know (lit. is the underlying-reason we (incl.) know) that we (incl.) are sinful.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “For there isn’t any person who can be considered righteous by God by means of his obeying the Law, because he always breaks the Law. The reason the Law was given was so that we (incl.) might see that we (incl.) break the Law of God.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Because there is no person whom God counts as righteous on account of his obeying the law, because the use of the law is only to make-known to a person that he has sin.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “Concerning all the good which is commanded by the law which the Jews follow, no one comes out that does it. Therefore whoever says that he lives according to what the law commands still cannot save his soul. Because God gives the law in order that we know that we have sin.” (Source: Tenango Otomi Back Translation)
