Following are a number of back-translations of Revelation 4:1:

• Uma: “After that, there was also something that I saw. I saw a door opened to/in heaven, and I heard a speaker speaking to me, like the one who spoke to me at the beginning earlier, that sounded like a trumpet. He said to me: ‘Come-up here! I will point out to you (sing.) what must happen when what you (sing.) saw earlier is past.'” (Source: Uma Back Translation)
• Yakan: “After that something else appeared to me. I saw a door opened there in heaven. And I heard again the voice like the sound of a tabuli’ that had spoken to me in the beginning. The voice said, ‘Come up here and I will show to you as to what is going to happen in the future’.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And then the Lord showed me something different again. I saw a door in heaven which was open. And there was someone speaking to me and that one speaking was the same one I heard before, whose voice sounded like the sound of a trumpet. And He said to me, ‘Come here and I will show you what must come to pass in the future.'” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “When that was finished, I saw-at-a-distance an entrance that was opened in/to heaven. I also heard the voice that I had previously heard like the loud-sound of a horn saying to me, ‘Come here so that I will show you (sing.) what will happen in a future day.'” (Source: Kankanaey Back Translation)
• Tagbanwa: “After that, something else was shown to me like it was being dreamed. For suddenly/unexpectedly I saw in heaven/sky an entrance which was open. Again I heard that voice which was like the sound of a horn. He said next to me, ‘Come up here, for I will show you the things which have been determined to happen.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “After those things which I saw, again I looked, looking up to heaven. I saw a door which was open. He who had spoken before to me, when he spoke to me it was like the blowing of a trumpet. He said to me: ‘Come here. I will show you what must happen afterwards,’ he said.” (Source: Tenango Otomi Back Translation)
