'Own' in the Bible

Angels who didn't keep their first domain, but deserted their own dwelling place, he has kept in everlasting bonds under darkness for the judgment of the great day.

wild waves of the sea, foaming out their own shame; wandering stars, for whom the blackness of darkness has been reserved forever.

They said to you that "In the last time there will be mockers, walking after their own ungodly lusts."
