Following are a number of back-translations of Matthew 21:27:

• Yakan: “Therefore they answered, they said, ‘We do not know as to where the authority of Yahiya was from.’ So-then Isa said to them, ‘Na, I also do not tell you where my authority comes from to do those things.'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “Therefore what they answered Jesus was, ‘We don’t know.’ And Jesus said again to them, ‘I also will not tell you what is my authority to do these things.'” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Then they said to Jesus, ‘We (excl.) don’t know.’ Jesus also said, ‘If that’s how it is, neither will I tell you who gave me my authority to be doing these-things.'” (Source: Kankanaey Back Translation)
• Tagbanwa: “That’s why they replied to Jesus, saying, ‘We don’t know.”Well, if it’s like that,’ said Jesus, ‘I won’t tell you either my authority to do these things I am doing.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “When they replied, they said to Jesus: ‘Concerning what John did, we do not know who gave him permission.’ Jesus said to them: ‘Well, you don’t tell me the word I ask you, then neither do I tell you who gave me permission to do what I do.'” (Source: Tenango Otomi Back Translation)
