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.
Genesis 9:21-23
21
He drank of the wine and got drunk. He was uncovered within his tent.
22
Ham, the father of Canaan, saw the nakedness of his father, and told his two brothers outside.
23
Shem and Japheth took a garment, and laid it on both their shoulders, went in backwards, and covered the nakedness of their father. Their faces were backwards, and they didn't see their father's nakedness.
