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.

7830. 'Speak to all the assembly of Israel, saying' means influx bearing instructions for all belonging to the spiritual Church. This is clear from the meaning of 'speaking' as influx, dealt with in 2951, 5481, 5743 (its further meaning as giving instructions - about the observances to be kept when they are delivered - is evident from what follows); and from the meaning of 'the assembly of Israel' as all truths and forms of good in their entirety. 'The assembly of Israel' is used to refer to all the tribes, by which all aspects of truth and good, or all aspects of faith and charity, are meant, see 7858, 7926, 4060, 6335. And as these are meant [by 'the tribes'], 'the assembly of Israel' means the spiritual Church, 6337; for truths and forms of good make the Church. For the representation of the spiritual Church by the children of Israel, see 6426, 6637, 6862, 6868, 7035, 7062, 7198, 7201, 7215, 7223.
