'Own' in the Bible

And angels that kept not their own principality, but left their proper habitation, he hath kept in everlasting bonds under darkness unto the judgment of the great day.

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

That they said to you, In the last time there shall be mockers, walking after their own ungodly lusts.
