Following are a number of back-translations of John 18:38:

• Uma: “Pilatus retorted: ‘Ah! What is that that you (sing.) call truth?’ After that, Pilatus went back outside and he said to the Yahudi people: ‘I did not find even one kind of his wrong.” (Source: Uma Back Translation)
• Yakan: “Pilatus said, ‘What is the truth?’ When Pilatus had said this, he went out again to the Yahudi and he said to them, ‘I cannot find any reason for judging this person.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And then Pilate said, ‘It would be good if someone knew what the true teaching is (but no one does).’ And then when he had said this, Pilate went out to the Jews, and he said to them, ‘I can’t find any sin that he’s done.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Whereupon Pilato said, ‘What perhaps is that-aforementioned truth?’ Then he again went-out and said to the Jews, ‘I know of no sin/crime of his.” (Source: Kankanaey Back Translation)
• Tagbanwa: “‘So what really is truth?’ asked Pilato. ‘No-one knows what is truth.’ When Pilato had said that, he went out again and said again to the Judio, ‘There’s nothing which I can whatever of sin in that person.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Pilate said to him, ‘Whoever can know about the true word?’ Having finished with the questioning, Pilate went outside to speak with the Jews. He said to them, ‘I do not find this man guilty of sin.” (Source: Tenango Otomi Back Translation)
