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.

1394. The perception which angels and spirits have is such that any one of them can know in an instant the nature of the love and faith in another Hence it is that according to their similarity with one another they are joined together into communities, and according to their dissimilarity they are withheld from such associations. And this is so completely the case that not even the smallest difference fails to draw them together or to set them apart. Consequently the communities in heaven are so distinct and separate from one another that it is impossible to envisage anything more distinct, such distinctness being determined by all the differences of love to and faith in the Lord, which are countless. This is how the heavenly form is produced, the nature of which is such that it presents itself as one human being. And this form is constantly being perfected.
