Following are a number of back-translations of Romans 9:29:

• Uma: “There is also a foretelling of the prophet Yesaya that says: ‘If for instance the Lord God who is powerful had not left/reserved for us a few descendants, we would have been really wiped out, like the inhabitants of Sodom and Gomora long ago.'” (Source: Uma Back Translation)
• Yakan: “It has been foretold also by Nabi Isaya long ago about the nation of Isra’il, he said, ‘If God, the one who rules all mankind, had not left us (incl.) descendants, we (incl.) would be like the people in the town Sodom and in the town Gomora, all dead.'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And this is like the former prophecy which Isaiah said, for He said, ‘If we (incl.) Jews had not been pitied by the powerful God, there wouldn’t even be a few of us left, for He would have wiped us out just like the people there in the towns of Sodom and Gomorrah.'” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “It is also like what he prophesied which preceded which says, ‘If the Highest God had not left-a few of us (excl.) Jews -remaining, we (excl.) would all have ceased-to-exist like what happened to those-from-Sodoma and those-from-Gomora.'” (Source: Kankanaey Back Translation)
• Tenango Otomi: “Isaiah again said: ‘God alone has power and if he did not pity the people then quickly would the Jews be finished off, just like when the people who lived in the cities of Sodom and Gomorrah were finished off.'” (Source: Tenango Otomi Back Translation)
