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.

8916. 'And the mountain smoking' means the good itself of truth, which cannot be perceived except in an outward form. This is clear from the meaning of 'the mountain', in this instance Mount Sinai, as Divine Good united to Divine Truth in heaven, dealt with in 8805; and from the meaning of 'smoking' as in an outward form. The reason why 'smoking' means this is that Divine Truth or the Word in its inward form is like the light and like a flame, whereas in its outward form it is like a cloud and like smoke. This is so because God's truth or the Word in its inward form is the nature of it as it exists in heaven, thus as it exists in the superior light of heaven, whereas the Word in its outward form is as it exists in the world, thus as it exists in the inferior light of the world; and the inferior light of the world compared with the superior light of heaven is like a cloud, or compared with its flame is like smoke. God's truth or the Word in its inward form is its internal sense, and in its outward form is its external or literal sense. The fact that the latter sense - the literal - is called 'the cloud', see Preface to Genesis 18, and 4060, 4391, 5922, 6343, 6752, 8106, 8781; and the reason why it is called 'smoke' is that 'smoke' means obscurity of truth, 8819. The mountain was seen to be smoking before the eyes of the children of Israel not because the Divine was such there, but - since the way in which the Divine appears to anyone who beholds Him depends on the character of the individual - because the character of those who were beholding Him was such that they considered worship to consist wholly in outward things and not at all in inward realities, as a consequence of which they understood the Word solely according to its literal sense. Therefore the Divine, in respect of the truth which was being declared, could not appear to them other than as smoke, that is, as obscurity. This also explains why it says that they stood afar off, by which the fact that they were remote from internal things is meant. But more of these matters below.
