Following are a number of back-translations of Matthew 12:39:

• Uma: “Yesus said: ‘No kidding the evil of all of you there! You always circumvent/wander-from God! You ask that I show you miracles. But no miracle will be shown to you. The only thing that will be shown to you will be a sign like what happened to the prophet Yunus long ago.” (Source: Uma Back Translation)
• Yakan: “But he answered them he said, ‘You people living today you are bad and you are not following God. You are asking for a sign, surprise. But you will be shown no sign except only the sign of Nabi Yunus of old.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And Jesus answered, ‘You people today, your customs are very bad. Love for God is no longer in your breaths. Why do you want to see a sign? The only sign that will be shown to you is like the sign which was performed long ago on the prophet Jonah.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “‘Oh you (expression of rebuke/frustration)!’ said Jesus answering. ‘The people now are very-bad, because they have turned-their -backs-on the true God. They insist that I show them an amazing sign, but nothing will-be-shown except (lit. if not) only the sign that is like what happened to Jonas the prophet back-before.” (Source: Kankanaey Back Translation)
• Tagbanwa: “Jesus replied saying, ‘As for all of you, your nature/ways are evil. You are like a married woman who is habitually-immoral who doesn’t have any concern for her marriage, for like that is what you are doing to God. You say you are asking for a sign, but nothing will be shown to you except that sign which was illustrated by what was experienced by the prophet of long ago who was Jonas.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “When Jesus answered, he said: ‘Concerning the people who live at this time, they have sins and do not know God, but first they must ask for miracles before they believe in me. Yet I will not do any miracle for people to see. What will take the place of a sign for the people is what happened to the prophet Jonah.” (Source: Tenango Otomi Back Translation)
