'Own' in the Bible

And angels who did not keep their own designated place of power, but abandoned their proper dwelling place, [these] He has kept in eternal chains under [the thick gloom of utter] darkness for the judgment of the great day,

wild waves of the sea, flinging up their own shame like foam; wandering stars, for whom the gloom of deep darkness has been reserved forever.

These people are [habitual] murmurers, griping and complaining, following after their own desires [controlled by passion]; they speak arrogantly, [pretending admiration and] flattering people to gain an advantage.

They used to say to you, “In the last days there will be scoffers, following after their own ungodly passions.”
