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.

7871. 'And will strike all the firstborn in the land of Egypt' means the damnation of those governed by faith separated from charity. This is clear from the meaning of 'striking' as damnation, for striking is killing or putting to death, and 'death' in the spiritual sense means damnation, see 6119; from the meaning of 'the firstborn' - when used in reference to the Egyptians, who represent those steeped in falsities arising from evil - as faith separated from charity, 3325, 7039, 7766, 7778, 7779. In the genuine sense the expression 'the firstborn', when it describes a feature of the spiritual Church, means faith that is wedded to charity, see 367, 2435, 3325, 3494, 6344, 7035; therefore in the contrary sense 'the firstborn' is faith devoid of charity.
