Following are a number of back-translations of Revelation 9:1:

• Yakan: “Then the fifth angel blew (the thing) like a tabuli’ that had been given to him. When he blew it, I saw a star, the one that had fallen from the sky onto the earth. To that star a key was given for opening the door of the bottomless hole.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “The fifth angel blew his trumpet and then I saw a star, which is to say, an angel who was on the earth because he had fallen from heaven. He was given the key which can open the pit whose depth has no end.” (Source: Western Bukidnon Manobo Back Translation)

• Tagbanwa: “Well, the fifth angel then blew his horn. There was like a star which I saw which fell here to the world from the sky. Given to him was the key to a very, very deep ravine which has no bottom (lit. nowhere arrived at).” (Source: Tagbanwa Back Translation)
