In the Bible, Egypt represents knowledge and the love of knowledge. In a good sense that means knowledge of truth from the Lord through the Bible, but in a natural sense it simply means earthly knowledge to be stored up and possessed. And even knowledge from the Bible is not always good: If we learn them with the goal of making them useful, then they are filled with angelic ideas. But they lack purpose when they are learned only for the sake of knowing things or for the reputation of being learned. So Egypt is a place you go to learn things, but to become heavenly you have to escape the sterile "knowing" and journey to the land of Canaan, where the knowledge is filled with the internal desire for good. It's interesting that when Egypt was ruled by Joseph, it was a haven for his father and brothers. This shows that when a person's internal mind rules in the land of learning, they can learn much that is useful. But eventually a pharaoh arose that didn't know Joseph, and the Children of Israel were enslaved. The pharaoh represents the external mind; when it is in charge the excitement and self-congratulation of knowing can reduce the internal mind to a type of slavery. The mind - like the Children of Israel - ends up making bricks, or man-made falsities from external appearances.

1023. That 'and I, behold I am establishing My covenant' means the Lord's presence in charity becomes clear from the meaning of 'a covenant', dealt with in 666, where it was shown that 'a covenant' means regeneration, and in particular the conjunction of the Lord with a regenerate person by means of love. It was also shown there that the heavenly marriage is the actual covenant itself, and that consequently the heavenly marriage exists with every regenerate person. The nature of this marriage or covenant has also been shown already.

[2] The heavenly marriage with the member of the Most Ancient Church existed in the area of his own will, but the heavenly marriage with the member of the Ancient Church came into existence in the area of his own understanding. Actually when the will part of man's mind had become utterly corrupted, the Lord in miraculous fashion separated the area of his own understanding from that corrupted will part, and within the area of man's own understanding He formed a new will, which is conscience. Into conscience He infused charity, and into charity innocence, and in this manner joined Himself to man, or what amounts to the same, established a covenant with him.

[3] To the extent that the area of a person's own will can be separated from this understanding part the Lord is able to be present with him, that is, to join Himself or establish a covenant with him. Temptations and similar means of regeneration render inactive the area of a person's own will, so that it is reduced to nothing and so to speak dies. To the extent that this happens the Lord can operate within charity by means of conscience implanted in the area of a person's own understanding. This is what is called 'a covenant' here.
