'Own' in the Bible

And angels who had not kept their own original state, but had abandoned their own dwelling, he keeps in eternal chains under gloomy darkness, to the judgment of the great day;

raging waves of the sea, foaming out their own shames; wandering stars, to whom has been reserved the gloom of darkness for eternity.

that they said to you, that at the end of the time there should be mockers, walking after their own lusts of ungodlinesses.
