Goats, as in Leviticus 16:21, 22, signify faith. Because man is regenerated by the Lord by the truth of faith, and consequently, his sins are removed and cast into hell, therefore it is said that "Aaron made the goat bear upon him all the iniquities of the children of Israel unto the land of separation, or into the wilderness." From correspondences, a goat signifies the natural man. The goat which was sacrificed, as in Leviticus 16:5-10, signifies the natural man regarding a part purified, and the goat which was sent into the wilderness regarding the natural man not purified.

7948. 'That Jehovah struck all the firstborn in the land of Egypt' means the damnation of faith separated from charity. This is clear from the meaning of 'striking as damnation, as in 7871; and from the meaning of 'the firstborn in the land of Egypt' as faith separated from charity, dealt with in 7039, 7766, 7778.
