Following are a number of back-translations of Romans 2:29:

• Uma: “Jews who are really God’s people, are people who are/become Jews in their hearts, and who are circumcised in their hearts. That means the work of the Holy Spirit in their hearts makes them God’s people, they did not become God’s people from their following written laws. People like that are the ones God praises. Even though men do not praise them, God will still praise them.” (Source: Uma Back Translation)
• Yakan: “But the real Yahudi, is a person whose liver has been made new by God’s Spirit. His following/obeying the law is not what makes his liver new. This person even if his fellow human beings do not praise him yet God praises him.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “In the same way also the true Jew is the person whose breath has been marked by God by means of the Holy Spirit and not by means of obeying the Law. And a person like this, it may be that he is not praised by his fellow men. However, he by contrast will be praised by God.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Because the true Jew, I mean to say, the true person of God, it is not the person who is like a Jew in appearance and in custom only but rather it is the person whose thoughts are right. The circumcision moreover that is valuable in God’s estimation, it is not the circumcision of part of the body but rather it is the removal of evil from a person’s mind which is the work of the Spirit of God, not the work of the written law. The person who is like this, even though his companions don’t praise him, God praises him nonetheless.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “He who truly is God’s people, is the one who sets his heart on separating from evil. This is the person whom God looks well upon, even though people don’t look well upon that person.” (Source: Tenango Otomi Back Translation)
• Mezquital Otomi: “But the true Jew is he who obeys God in his heart, and that true sign in that which is inside a clean heart. This true sign is that which God does in one’s life principle, it is not that made in the body as written in the law. People will elevate the honor of the Jews just in appearance, but God is the one who will elevate the honor of those who are truly Jews in their hearts.” (Source: Waterhouse / Parrott in Notes on Translation October 1967, p. 1ff.)
