'Own' in the Bible

And [the] angels who did not keep to their own domain but deserted their proper dwelling place, he has kept in eternal bonds under deep gloom for the judgment of the great day,

wild waves of the sea foaming up their own shameful deeds, wandering stars, for whom the deep gloom of darkness has been reserved for eternity.

for they said to you, "In the end time there will be scoffers following according to their own ungodly desires."
