Following are a number of back-translations of Matthew 17:20:

• Uma: “Yesus said: ‘[Of course] it was like that, because your faith is so little. I say to you: if we (incl.) have faith, even just a chigger’s-worth, there would not be anything that would not happen. We (incl.) could say to that mountain over there: ‘Move from there,’, and it would certainly move.” (Source: Uma Back Translation)
• Yakan: “Isa said, ‘The reason that you could not drive him out is, because your trust in God is very little. I tell you truly, if you trust in God only just a little bit, figuratively just like the size of a mustard seed, and you tell the mountain to transfer/move, it will really transfer/move. Nothing is difficult for you if you trust. (” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “‘You couldn’t heal him,’ answered Jesus, ‘because your faith is so small. Remember that if you have faith, even just a little bit like a mustard seed, you can say to this hill that it be transferred, and it will obey you. You can do anything.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “‘Because your faith is lacking,’ said Jesus answering. ‘This that I say to you is true that even if your faith is small like the smallest seed, it is possible for you to say to this mountain, ‘Move-over there,’ and it will truly move-over. There is absolutely nothing that you can’t do!” (Source: Kankanaey Back Translation)
• Tagbanwa: “Jesus replied saying, ‘Because your belief-in/obeying-of me is still lacking. Hopefully your belief can be like a small seed of mustasa’ which keeps on growing till it is a big plant. For this it true which I will say to you, if your belief in me is like this, really even supposing you say to that hill to move, it’s certain that it will obey you. There’s nothing you won’t have ability for as long as your trust and belief are firmly-founded in me.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Jesus said to his learners: ‘You couldn’t because you were not sure in your hearts that he would be healed. Truly I tell you that if you have just a little faith, even though it is no bigger than the small seed of mustard, then you would be able to say to the mountain there: ‘Leave from where you are, mountain, go to the other side,’ you would say. And the mountain would leave. Nothing is impossible if you have a little faith.” (Source: Tenango Otomi Back Translation)
