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.

3281. 'And Isaac was a son of forty years' means from His own power by means of the conflicts brought about by temptations. This is clear from the representation of 'Isaac' as the Divine Rational, often dealt with already, from the meaning of 'forty' as temptations, dealt with in 730, 862, and from the meaning of 'years' as states, dealt with in 23, 487, 488, 493, 893, 2788. Consequently the internal sense of these words is that the Lord made His Rational Divine even as regards truth by means of the conflicts brought about by temptations, and so by His own power. For the Lord by His own power made everything human within Himself Divine by means of the temptations He underwent, as has been shown already in 1661, 1663, 1668, 1690, 1787, 2083, 2523, 2632, 2776, 3030, 3043, 3141.
