Following are a number of back-translations of Romans 3:21:

• Uma: “But at this time, God shows us the/his way that men can become straight in his sight. In the Book of the Lord’s Law and in the letters of the prophets long ago is already foretold the way God makes us straight. But we do not become straight in his sight from our following the Lord’s Law.” (Source: Uma Back Translation)
• Yakan: “But now God has made known to us (dual) as to how our (dual) sins can be forgiven so that he considers/regards us (dual) as straight. And this is not because of our (dual) following the law. It was hep written in the law of Musa and in the holy-book of the prophets as to how so that our (dual) sin can be forgiven.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And now God has allowed us (incl.) to understand the way by which He can consider us righteous. And this is not by means of obeying the Law; however, this way is spoken about in the word of God which was written long ago.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “But now, God’s plan to count people as righteous in his sight has been made-known, but it’s not because of their obeying the law. This plan of his which indeed also was spoken of in what Moses and the other prophets wrote, it is this.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “So now the good news tells about how God clears our sins. Now it is seen that God clears our sins, it isn’t the law followed by the Jews which clears them. There in the law God’s prophets predicted the word that there would come the day when God would save us.” (Source: Tenango Otomi Back Translation)
