Following are a number of back-translations of Acts 14:15:

• Uma: “‘What-in-the-world is this you are doing? We(excl.) here are ordinary men also, like you. Our(excl.) coming here is to bring the Good News to you, so that you stop worshipping those lords that have no use, and so you worship the God who Lives, the God who made the sky, world, sea, with all its contents.” (Source: Uma Back Translation)
• Yakan: “they said, ‘Why do you do this to us (excl.)? We (excl.) are just humans like you. And the reason we (excl.) came here is to tell you the good news in order that you will turn-your-backs-on/reject those your gods, those useless ones. We (excl.) came in order that you will change to follow the living God, the God who created the sky and the earth, the sea and everything in it.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “‘Why are you worshipping us, brethren? We are just people. We are human beings just like you. We came here to your village so that we might cause you to understand about the good news so that you might have done with these customs which have no purpose and so that you might also believe in the God which has no death. He is the one who created heaven and earth and the sea and all of the contents of these.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “‘Stop, companions! Why are you doing that? We (excl.) are only people just like you. We (excl.) have come here to tell you the good news concerning the Lord Jesus, in order that you will turn-your -backs-on those false/imitation gods that have no purpose in order to believe/obey the living God who made the sky and the earth and the ocean and everything that is there.” (Source: Kankanaey Back Translation)
• Tagbanwa: “‘All of you, please don’t do this. For as for us (excl.), we are indeed people/human like you. We(excl.) are making known to you that you must now let go of those which you worship which has truth/reality to it, for nothing can be gained by it. You must now submit to God who is really alive, he who created heaven/sky and the world/land and the sea, including all their contents.” (Source: Tagbanwa Back Translation)
