Following are a number of back-translations of Jude 1:6:

• Uma: “Remember also the angels long ago in heaven. Some of them went-beyond the bounds of their authority/power, and they left their dwelling-place. The Lord bound those angels with chains that can never be broken, he confined them in a dark dwelling-place. There they are kept confined until the time comes for him to decide their case on the terrifying day of punishment.” (Source: Uma Back Translation)
• Yakan: “And also remember the angels who left/gave-up the authority that God had given them and who left the place where God had established them. They are chained forever and they are imprisoned by God in utter darkness until the great day comes when God judges them.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “Consider also his angels long ago in heaven. They abandoned the position he had given them, and they left their true dwelling place. Because of that, he imprisoned them in a very dark place. He has bound them with chains that cannot be destroyed forever, for they are being made to wait until the day in the future when he will punish them.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Remember also the angels who were not content with the position that God gave them but rather they left/abandoned their proper dwelling-place in heaven. On-account-of their doing that, God chained them with chains that cannot be removed and he imprisoned them in the place of darkness below until the important/valued day when-he-will-judge them.” (Source: Kankanaey Back Translation)
• Tagbanwa: “Consider also the angels who didn’t hold fast to the job/responsibility God determined for them. Isn’t it so that they left their own place where they lived? That’s why they were caused by God to be bound in chains forever. And he imprisoned them in a place-of-darkness till they will be sentenced to judgment, at the coming of the far-from-ordinary day when judging is done.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “And remember what happened to those angels who didn’t respect the work they had, but left their work there in heaven. God has fastened them with chains in the darkness until the day comes when there will be the judgment.” (Source: Tenango Otomi Back Translation)
