Arcana Coelestia # 7871
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.

3326. 'Esau said, Behold, I am going to die' means that [the good of the natural] would after that rise again. This is clear from the representation of 'Esau' as the good of the natural, dealt with in 3302, 3322, and from the meaning of 'dying' as the final phase of a state when something ceases to exist, dealt with in 2908, 2912, 2917, 2923. And since the end of the previous state is the beginning of the next, 'going to die', like 'being buried', here means rising again after that. For 'being buried' means rising again, see 2916, 2917, 3256. His rising again after that implies that good will come to have priority and dominion over truth, after truth in the short term has apparently had priority, dealt with above.
