Following are a number of back-translations of Matthew 26:31:

• Uma: “Yesus said to them: ‘Tonight all of you, your faith in me will be shaken, for it is written in the Word of God like this: ‘I will kill the shepherd, and the sheep of his care will scatter.'” (Source: Uma Back Translation)
• Yakan: “So-then Isa said to them, ‘This night all of you will leave me, for this is written in the holy-book, ‘I commanded/told the one who looks after the sheep to be killed, so-then his sheep scattered.'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And Jesus said to them, ‘All of you, your faith in me will become weak tonight because of what happens to me. Because there is a written saying of God which says, ‘I will kill the one caring for the sheep, and they will be scattered.'” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “When they were on the path, Jesus said to them, ‘During this night, in-the-future indeed (prophetic formula) you will all leave-me and run-away, because there is something God caused-to-be-written that says, ‘Later I will kill the one-who-takes-care of the sheep and they will be separated.'” (Source: Kankanaey Back Translation)
• Tagbanwa: “Included in what Jesus said that night was his warning, saying, ‘This night, as for all of you, your belief-in/obeying-of me will be lacking. You will leave/desert me. For like what was written which is the word of God, which says, ‘I will kill the shepherd. Therefore what will happen to the sheep is that they will be scattered.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Jesus said to his learners: ‘All of you will desert me this night. Because it will happen like it says in the Holy Book which says: ‘I will cause that the shepherd will die. The sheep then will scatter,’ it says.” (Source: Tenango Otomi Back Translation)
