Following are a number of back-translations of Revelation 21:8:

• Uma: “But people who are afraid to follow me or who do not believe, people whose deeds are evil, killers, those who do [sexual] wrong, sorcerers, those who worship idols, and all who lie, they are certainly punished in the sea of fire that blazes and has-coals. That is what is called the second death.'” (Source: Uma Back Translation)
• Yakan: “But the ones who turn-their-back-on/reject me because of their fear of persecution/suffering and those who give up their trust in me, they will be thrown into the sulphur fire. Likewise also all who do bad, and kill, and practice illicit sex, and do sorcery towards their companions, and worship idols, and all liars, that is their portion they will be put in the sulphur fire large like a lake. This is called the second death.'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “But he who is afraid to follow Me, and the unfaithful persons, the people whose actions are vulgar, murderers, and those with filthy customs, sorcerers, and all those who worship false gods, and all people who are liars, what their end will be is: they will be thrown into the lake filled with flaming sulphur which is the second death,’ He said.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “But the person who doesn’t persevere in believing due to his fear of hardship/suffering, the one who has no faith, the one whose behavior is filthy, the murderer, the one who sleeps-with someone who is not his spouse, the sorcerer and spirit-medium, the one who worships idols, and all who tell-lies, they will all stay in the wide pool which is the place of flaming sulfur. This is what is designated as the second death.'” (Source: Kankanaey Back Translation)
• Tagbanwa: “But well, really very hard is what will happen to those who are afraid to believe, those who dropped/gave-up their believing, those who let-themselves-be-captivated by disgusting doings, killers of their fellowman, those behaving-immorally with one who is not their spouse, those who have secret-supernatural-skills which are occult-powers, the ones who serve familiar-spirits or whatever is their replacement for God, and all who are liars. All of these, without any uncertainty, will be thrown into that lake of burning asupri, this being what is referred to as the second death.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “But the people who fear to suffer on account of me, and those who separate from my word, those who are evil people, who are killer, who commit fornication, who are witch doctors, who worship idols, who are liars, these have coming to them that they will go to lake bubbling burning fiercely with sulphur. That is the time of death.'” (Source: Tenango Otomi Back Translation)
