Arcana Coelestia #3326
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.
Exodus 34:19-20
19
"All that opens the womb is mine; and all your livestock that is male, the firstborn of cow and sheep.
20
The firstborn of a donkey you shall redeem with a lamb: and if you will not redeem it, then you shall break its neck. All the firstborn of your sons you shall redeem. No one shall appear before me empty.
