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.

244. And the fourth living creature was like a flying eagle. This symbolizes the Divine truth of the Word in respect to its concepts and the understanding they afford.

Eagles have various symbolic meanings, but flying eagles symbolize concepts which lead to understanding, since when they fly, they recognize and see. They also have sharp eyes so as to see keenly, and eyes symbolize the intellect (nos. 48, 214).

To fly means, symbolically, to perceive and teach, and in the highest sense, which has the Lord as its subject, it means to foresee and provide.

That this is the symbolic meaning of eagles in the Word is apparent from the following passages:

Those who wait on Jehovah shall renew their strength; they shall mount up on wings like eagles. (Isaiah 40:31)

To mount up on wings like eagles means to be raised into concepts of truth and goodness and so into intelligence.

Does the hawk fly by your wisdom...? Does the eagle mount up at your command...(and) spy out its food? Its eyes observe from afar. (Job 39:26-27, 29)

The eagle here describes a faculty for recognizing, understanding, and foreseeing, and the fact that this does not result from one's own intelligence.

(Jehovah,) who satisfies your mouth with good, so that you are renewed in your youth like an eagle. (Psalms 103:5)

To satisfy the mouth with good means to give understanding by means of concepts. Thus an analogy is made with an eagle.

A great eagle with large wings and long pinions... came upon Lebanon and took from the cedar a little branch... Then it took some of the seed of the land and planted it in the field of a growing crop..., and it grew and became a vine... But there was another great eagle..., to which the vine bent its roots... (Ezekiel 17:1-8)

The two eagles here describe the Jewish and Israelite churches, each in respect to its concepts of truth and consequent intelligence.

In an opposite sense, however, eagles symbolize false concepts, by which the intellect is corrupted, as in Matthew 24:28, Jeremiah 4:13, Habakkuk 1:8-9, and elsewhere.
