Arcana Coelestia #624
624. It is clear that a state which is not a state of the Church is the subject here from the fact that in this verse and those that follow in chapter the name God is used, whereas in previous verses it was Jehovah. When the Church does not exist the name God is used, but when it does exist, it is Jehovah; for example in Genesis 1, when the Church did not exist, He was called God, but in the next chapter when it did, He was called Jehovah God. 'Jehovah' is the holiest of names, and belongs to the Church alone. Not so 'God', for no nation was without gods. Consequently the same holiness was not attached to the name God. Nobody was allowed to utter the name Jehovah except him who had knowledge of the true faith; but anyone was allowed to utter the name God.
Arcana Coelestia #5301
5301. 'Which there will be in the land of Egypt' means which will exist in the natural. This is clear from the meaning of 'the land of Egypt' as the natural mind, dealt with in 5276, 5278, 5279, 5288. The expression 'the natural' is used here and in other places, and by it the natural mind is meant. For the human being has two minds, the rational mind and the natural mind. The rational mind belongs to the internal man, whereas the natural mind belongs to the external man; and it is the natural mind or external man that is meant when simply 'the natural' is used. The mind is a person's true self, as will be seen in what is spoken about next.
