Arcana Coelestia #23
23. Nothing is more common in the Word than for the word 'day' to be used to mean the particular time at which events take place, as in Isaiah,
The day of Jehovah is near. Behold, the day of Jehovah comes. I will make heaven tremble, and the earth will be shaken out of its place, on the day of My fierce anger. Its time is close at hand, and its days will not be prolonged. Isaiah 13:6, 9, 13, 22.
And in the same prophet,
Her antiquity is in the days of antiquity. On that day Tyre will be forgotten for seventy years, like the days of one king. Isaiah 23:7, 15.
Since 'day' stands for the particular time it also stands for the state associated with that particular time, as in Jeremiah, Woe to us, for the day has declined, for the shadows of evening have lengthened! Jeremiah 6:4
And in the same prophet,
If you break My covenant that is for the day and My covenant that is for the night, so that there is neither daytime nor night at their appointed time. Jeremiah 33:20, 25.
Also,
Renew our days as of old. Lamentations 5:21.
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.
