There’s a curious verse in the epistle of Jude (KJV) that refers to the “first estate.” Nothing further is mentioned, nor is there any other reference to it in the entire Bible. Even so, I think we can make some assumptions regarding this verse.
“And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.” (Jude 6).
