'Own' in the Bible

You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day.

These people are grumblers and fault-finders who go wherever their desires lead them, and they give bombastic speeches, enchanting folks for their own gain.

For they said to you, "In the end time there will come scoffers, propelled by their own ungodly desires."
