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.

10310. 'Will be cut off from his people' means separation from heaven and the Church, and spiritual death. This is clear from the meaning of 'being cut off from his people' as separation and spiritual death, dealt with in 10288. The fact that it is a separation from heaven is clear from what has been stated immediately above in 10309; and the reason why it is a separation from the Church as well is that they alone are true members of the Church who have the Church within them, and they have the Church within them who have an affection for truth for its own sake and an affection for good for its own sake, thus who are governed by love towards the neighbour and love to God. For good and truth are the neighbour, and so is God since good and truth are God's and so are God as He exists with such people. Those who are not like this are not true members of the Church, even though they may be within the Church.
