Following are a number of back-translations of Acts 2:40:

• Uma: «Many other were the word of Petrus to the crowd, he advised them and warned them, he said: ‘Repent! No longer follow the evil people who live at this time, so that you do not receive the punishment of God that will strike them.'» (Source: Uma Back Translation)
• Yakan: «Petros said much more to them and he begged them, he said, ‘Help yourselves so that you will not be punished like the people now/of these days who are bad/evil.'» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «And there were many arguments which Peter used to advise them. He said, ‘Avoid the punishment of God on these people today whose customs are bad.'» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «There was much more that Pedro said, advising and warning them so that they would hopefully be-persuaded. ‘You should escape the punishment of the stubbornly-unteachable people nowadays,’ he said.» (Source: Kankanaey Back Translation)
• Tagbanwa: «Much more was said by Pedro which was his testimony and warning and he spoke-emphatically to them, saying, ‘Now make sure that you will be saved, no longer included with people whose nature/ways are evil, who really will be punished by God.'» (Source: Tagbanwa Back Translation)
• Desano: «He said many things to them, speaking well to them, seeking the good of the people so that they would not be mixed with the evil people.»
• Isthmus Mixe: «Peter told them many more words. They were thus counseled: ‘Turn away from evil people lest you perish with them.'»

San Mateo del Mar Huave: «And in regard to that he told them more, he gave them advice, he said: ‘You leave off that which is wicked, that which all the people do.’ he tells them.» (Source for this and two above: Viola Waterhouse in Notes on Translation August 1966, p. 86ff.)
