414. So that a third of the day did not shine, and likewise the night. This symbolically means that they no longer have in them any spiritual truth or natural truth from the Word serviceable for doctrine and life.

The day's not shining means that they had no light from the sun, and "likewise the night" means that they had no light from the moon and stars. Light in general symbolizes Divine truth, which is truth from the Word. The light of the sun symbolizes spiritual Divine truth, and the light of the moon and stars symbolizes natural Divine truth, both acquired from the Word. Divine truth in the spiritual sense of the Word is like the light of the sun during the day, and Divine truth in the natural sense of the Word is like the light of the moon and stars at night. The spiritual sense of the Word, moreover, flows into its natural sense, as the sun does with its light to the moon, and this reflects the light of the sun indirectly.

In this way also does the spiritual sense of the Word enlighten people, even people who know nothing of that sense, when they read the Word in its natural sense. However, it enlightens a spiritual person as light from the sun does his eye, but a natural person as light from the moon and stars does his eye. Everyone is enlightened in accordance with his spiritual affection for truth and goodness, and at the same time in accordance with the genuine truths by which he has opened his rational faculty.

[2] Day and night also have this meaning in the following places:

God said, "Let there be lights in the firmament of the heavens to divide the day from the night...." Then God made two great lights: the greater light to rule by day, and the lesser light to rule by night. He made the stars also. And God set them in the firmament of the heavens to give light on the earth, and to rule by day and by night, and to divide the light from the darkness. (Genesis 1:14-19)

(Jehovah) made great lights..., the sun to rule by day..., the moon and stars to rule by night... (Psalms 136:7-9)

The day is Yours, (O Jehovah,) the night also is Yours; You have prepared the light and the sun. (Psalms 74:16)

...Jehovah... gives the sun for a light by day, the ordinances of the moon and the stars for a light by night... (Jeremiah 31:35)

If you can break My covenant with the day and My covenant with the night, so that there will not be day and night in their season, then My covenant also may be broken with David My servant... If I have not appointed My covenant with day and night, the ordinances of heaven and earth, I also will reject the offspring of Jacob and David... (Jeremiah 33:20-21, 25-26)

I cite these passages to make known that the darkening of both kinds of light is meant.

5194. 'And it happened at the end of two years of days' means after the state when the joining together took place, that is to say, when the powers of the senses belonging to the exterior natural and those belonging to the interior natural were joined together, both of which powers are dealt with in the previous chapter. This is clear from the meaning of 'two years of days', that is, a period of two years, as a state involving a joining together; for 'two' means a joining together, 1686, 3519, while 'years' means states, as does 'days'. For the meaning of years' as states, see 487, 488, 493, 893, and for that of 'days', 27, 487, 488, 497, 2788, 3462, 3785, 4850. The reason 'two' means a joining together is that every single thing in the spiritual world, and consequently in the natural world, has two forces associated with it - goodness and truth. Good is an active inflowing force, truth a passive, recipient one. Also, because everything has these two forces associated with it, and because nothing can ever be brought forth unless the two are made one by becoming so to speak married to each other, a joining together is therefore meant by them.

[2] This type of marriage exists in every single thing within the natural order and its three kingdoms; without it nothing whatever can come into existence. For anything to come into existence within the natural order there needs to be heat and light, heat in the natural world corresponding to the good of love in the spiritual world, and light corresponding to the truth of faith. These two - heat and light - must act as one if anything is to be brought forth. If they do not act as one, as is the case in winter-time, nothing at all is brought forth. The same holds true on a spiritual level, as is quite evident with the human being, who has two mental powers - will and understanding. The will has been formed so that it may receive spiritual heat, that is, the good of love and charity, while the understanding has been formed so that it may receive spiritual light, that is, the truth of faith. Unless these two residing with a person make one nothing is brought forth, for the good of love devoid of the truth of faith cannot give definition and particular character to anything, while the truth of faith devoid of the good of love cannot bring anything into effect. So that the heavenly marriage may exist in a person therefore, or rather so that a person may be in the heavenly marriage, those two entities must make one in him. This explains why the ancients likened every single thing in the world, and every single thing within the human being, to a marriage, 54, 55, 568, 718, 747, 917, 1432, 2173, 2516, 2731, 2739, 2758, 3132, 4434, 4875, 5138. From all this one may see why it is that 'two' means a joining together.
