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.

7240. 'And so it was on the day Jehovah spoke to Moses in the land of Egypt' means the state of the Church at that time, when the command was given through the law from God to those who belonged to the Lord's spiritual kingdom, when they were still in close proximity to those in hell. This is clear from the meaning of 'the day' as the state, dealt with in 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, 6110, here the state of the Church since that is the subject; from the meaning of 'Jehovah speaking' as the command, here the command given to those who belonged to the Lord's spiritual kingdom; from the representation of 'Moses' as the law from God, dealt with in 6771, 6827; and from the meaning of 'the land of Egypt' as the place where those who belonged to the Lord's spiritual kingdom were molested by falsities. This place was on the lower earth, which is next to the hells, see 7090. 'The land of Egypt' where the children of Israel were, and which was called Goshen, means that lower earth; but the place where the Egyptians were means the surrounding hells, the source of the molestations by falsities.
