Following are a number of back-translations of 2 John 1:9:

• Uma: “All people who wander/detour from the true teaching, and they do not follow the teaching of Kristus, those people are not connected with God. People who remain following the teaching of Kristus, they are connected with God the Father and with God the Child.” (Source: Uma Back Translation)
• Yakan: “Whoever does not remain/stick-to the teaching of Almasi but goes beyond (it), God is not there with him. Whoever stays/remains with the teaching of Almasi, both the Father and the Son are with him.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “If there is a person who has abandoned the true doctrine taught by Christ so that he might hold fast to a false doctrine that he has added on, he has not become one with God. Anyone, by contrast, who holds fast to the true doctrine, he is the one who has been made one with our Father God and His Son.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Any person, if he doesn’t continue to follow what Cristo taught, but rather exceeds it, he doesn’t know God. But the one who carries-on in following what Cristo taught, God the Father and his Child also are in him.” (Source: Kankanaey Back Translation)
• Tagbanwa: “As for the one who is not holding fast to the teaching of Cristo, because he is (emphatic) overriding it, he is really far from God. However, whoever is holding fast to this teaching of Cristo, he is really being held fast to by God the Father and Son.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Concerning the person who does not want to say only what Christ taught, but speaks other words which Christ did not teach, he is a person who does not walk with God. But the person who speaks only what Christ taught is one who walks with the Father and also with the Son of God.” (Source: Tenango Otomi Back Translation)
• Yatzachi Zapotec: “Any of us if we are forsaking what Christ taught us and are taking another road, God is not with us. But if we are constantly heeding what Christ taught us, our father God and his son are with us.”
• Eastern Highland Otomi: “But whoever wants to go beyond (outdo) God’s teaching, and doesn’t want to remain in the teaching of Christ, but then he isn’t with God. But he who remains in the teaching of Christ, he is with the Father, and also with his Son.”
• Isthmus Zapotec: “Whoever goes another direction (all one verb stem) and no longer follows what Christ taught does not know (is not acquainted with)God. But whoever follows what Christ taught, he truly knows God the Father and His Son.”
• Sayula Popoluca: “He who goes astray after another doctrine and doesn’t remain (stay with) Christ’s doctrine, he doesn’t have fellowship with God . . ..” (Source for this and three above: John Beekman in Notes on Translation 12, November 1964, p. 1ff.)
