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.
Deuteronomy 30:11-14
11
For this commandment which I command you this day, it is not too hard for you, neither is it far off.
12
It is not in heaven, that you should say, "Who shall go up for us to heaven, and bring it to us, and make us to hear it, that we may do it?"
13
Neither is it beyond the sea, that you should say, "Who shall go over the sea for us, and bring it to us, and make us to hear it, that we may do it?"
14
But the word is very near to you, in your mouth, and in your heart, that you may do it.
