Following are a number of back-translations of Revelation 17:9:

• Uma: “‘That is why we need to think as clearly as possible so that we understand the meaning of the figure of speech. The seven heads of the animal stand for seven mountains that the woman sits on. And the seven heads also stand for seven kings.” (Source: Uma Back Translation)
• Yakan: “The angel also said, ‘What I am now explaining can be understood by people of deep intelligence. The meaning of that creature’s seven heads is seven hills, that is the sitting-place of that bad woman. Its meaning is also seven kings.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “A wise person with a good head will be able to understand this. The interpretation of the seven heads of the beast are seven hills where the woman sits, which is to say, the famous city. That is not all, because the seven heads are also seven kings.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Then the angel continued to say, ‘It requires a wise/intelligent and thoughtful/reflective person to be able-to-understand this. The meaning of the seven heads, it is seven mountains on-which-the woman -is-seated.” (Source: Kankanaey Back Translation)
• Tagbanwa: “Really a quick mind (lit. softness of head) and wisdom/understanding is needed here. Those seven heads, they are the seven hills on which that woman is sitting.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Concerning the words here, it is wanted that the thinking of the person be firm in order to understand about this word. These seven heads of the terrible animal come out to mean seven hills which serve for a seat for the woman.” (Source: Tenango Otomi Back Translation)
