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.

TEACHINGS ABOUT CHARITY
No one can know what good is, good understood in a spiritual sense, unless he knows what love towards the neighbour and love to God are; and no one can know what evil is unless he knows what self-love and love of the world are. Neither can anyone within himself acknowledge and therefore know what truth composing faith is unless he knows what good is and is governed by it; nor can anyone know what falsity is unless he knows what evil is. No one therefore can engage in self-examination unless from the two kinds of love that go with good he knows what good is, and from good what truth is, and unless from the two kinds of love that go with evil he knows what evil is, and from evil what falsity is.
