Arcana Coelestia #165
165. The nakedness of which they were not ashamed means innocence. This is quite clear from what follows. When integrity and innocence left them they were then ashamed of their nakedness, and it seemed disgraceful to them, and so they hid themselves. It is additionally clear from the things represented in the world of spirits that the nakedness of which they were not ashamed means innocence. Indeed when spirits wish to exonerate themselves and prove that they are blameless they present themselves naked to witness their innocence. This is particularly clear with the innocent in heaven, who look like young children, naked, and wearing garlands round them that accord with their particular variety of innocence. But those who do not possess so much innocence appear clothed in splendid and shining clothes - you might call them brightest silk - like angels when seen from time to time by the prophets.
Ezekiel 23:8-10
8
Neither has she left her prostitution since [the days of] Egypt; for in her youth they lay with her, and they handled the bosom of her virginity; and they poured out their prostitution on her.
9
Therefore I delivered her into the hand of her lovers, into the hand of the Assyrians, on whom she doted.
10
These uncovered her nakedness; they took her sons and her daughters; and her they killed with the sword: and she became a byword among women; for they executed judgments on her.
