Following are a number of back-translations of Matthew 9:15:

• Uma: “Yesus answered them with this parable, he said to them: ‘People at a wedding feast definitely are happy together with the groom, they do not fast while the groom is still with them. But the time will come when the groom is taken from among them. At that time, only then will they fast.'” (Source: Uma Back Translation)
• Yakan: “Isa answered them in a parable. He compared his disciples to people at a wedding. He said, ‘Are the people at a wedding sad/troubled as long as the bridegroom is still there with them? No. But in the future when the bridegroom has been caused to leave then they will fast.'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “Jesus answered, ‘If there is a wedding, it cannot be that the companions of the bridegroom will not join in the festivities while the bridegroom is still with them. But at the time when the bridegroom leaves them, they will abstain from eating. In the same way also, while I am still here with them, they will not abstain from eating.'” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Jesus answered parabling, ‘If someone has-a-wedding, do you think do-you-suppose that the groom’s (lit. one-marrying) friends whom he invited ought to be sad? But when the time arrives that the bridegroom will be taken-away from them, that’s the time-when-they -will-fast.'” (Source: Kankanaey Back Translation)
• Tagbanwa: “Jesus replied saying, ‘Is it possible/acceptable for the ones invited to a wedding to be sad as long as the man whose marriage is being celebrated is with them? Surely not. Well it’s like that too with these disciples of mine. But the day will come when I will be separated from them. And then they will fast.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Jesus said to those who were speaking to him: ‘People who have been called to view the marriage are not sad and fasting while the bridegroom is right there with them. Like that, my learners also do not fast while I am with them. But there is coming the day when my enemies will take me away. Of course on that day they will have reason to fast.” (Source: Tenango Otomi Back Translation)
• Ebira: “Jesus said to them: ‘Can the people (the relatives and friends of) a man, who is in the process of getting a wife, mourn while the husband is with them? They cannot fast when the husband of the girl is with them.'” (Ebira does not have formal terms for “wedding,” “groom,” and “bride”) (Source: Hans-Jürgen Scholz in Holzhausen 1991, p. 34)
