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.
Genesis 48:17-20
17
When Joseph saw that his father laid his right hand on the head of Ephraim, it displeased him. He held up his father's hand, to remove it from Ephraim's head to Manasseh's head.
18
Joseph said to his father, "Not so, my father; for this is the firstborn; put your right hand on his head."
19
His father refused, and said, "I know, my son, I know. He also will become a people, and he also will be great. However, his younger brother will be greater than he, and his seed will become a multitude of nations."
20
He blessed them that day, saying, "In you will Israel bless, saying, 'God make you as Ephraim and as Manasseh'" He set Ephraim before Manasseh.
