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.

681. And it became blood as though of a dead man, and every living creature in the sea died. This symbolizes the infernal falsity in those people by which every truth in the Word was extinguished, and so also every truth in the church and in faith.

Blood as though of a dead man, or blood oozing and mixed with pus, symbolizes infernal falsity. For blood symbolizes Divine truth, and in an opposite sense, that truth falsified (no. 379). But blood as though of a dead man symbolizes infernal falsity, inasmuch as death symbolizes the extinction of spiritual life, and so a dead man symbolizes something infernal (nos. 321, 525). That every living creature died means symbolically that every truth in the Word, in the church, and in faith was extinguished. For a living creature symbolizes the truth of faith; accordingly a living creature that has died symbolizes the truth of faith extinguished.

A living creature in the Word, or a soul when referring to a human being, symbolizes his spiritual life, which is also the life of his intellect; and because the intellect is formed by truths, and truths have to do with faith, therefore a living creature or soul symbolizes the truth of faith. That this is the symbolic meaning of a living creature or soul can be seen from many passages in the Word, and also from those that mention both soul and heart. The soul and heart plainly mean a person's life, but it is his life in consequence of his will and intellect, or spiritually speaking, in consequence of his love and wisdom, or of his charity and faith; and the life of the will springing from the goodness of love is meant by heart, while the life of the intellect springing from truths of wisdom or of faith is meant by soul. These are meant by soul and heart in Matthew 22:37, Mark 12:30, 33, Luke 10:27; Deuteronomy 6:5; 10:12; 11:13; 26:16; Jeremiah 32:41; and elsewhere. Also in passages which mention heart by itself and soul by itself.

The reason these terms are used comes from the correspondence of the heart with the will and love, and of the soul's action in the lungs with the intellect and wisdom, as may be seem in Angelic Wisdom Regarding Divine Love and Wisdom, Section Five, where this correspondence is discussed.
