'Edom' or 'Idumea,' as in Isaiah 34:5, signifies people who are in evil and falsities derived there.

(Reference: The Inner Meaning of the Prophets and Psalms 34)

2322. That 'Sodom' means the evil, especially those inside the Church, is clear from the meaning of 'Sodom' as evil that stems from self-love, dealt with in 2220, 2246. It means therefore people who are governed by such evil. People who understand the Word purely from the sense of the letter may imagine that 'Sodom' is used to mean a certain kind of foul behaviour that is totally unnatural, but in the internal sense 'Sodom' means evil that springs from self-love. Out of this evil all evils of every kind well up. And the evils that well up from it are in the Word called 'adulteries' and are described as such. This will be clear from those places in the Word which will be quoted at the end of this chapter.
