414. That the day shone not for a third part of it, and the night likewise, signifies that there is no longer any spiritual truth nor natural truth serving for doctrine and life from the Word with them. By "the day not shining," is meant that there was no light from the sun; and by "no night likewise," is meant that there was no light from the moon and stars. By "light," in general, is signified the Divine truth, which is truth from the Word; by "the light of the sun," Divine truth spiritual; and by the light of the moon and stars, the Divine truth natural, both from the Word. The Divine truth, in the spiritual sense of the Word, is like the light of the sun by day; and the Divine truth in the natural sense of the Word, is like the light of the moon and stars by night. The spiritual sense of the Word also flows into its natural sense as the sun does with its light into the moon, which gives forth the light of the sun in a mediate manner. In the same way does the spiritual sense of the Word enlighten men, even those who know nothing at all concerning it, whilst they read the Word in its natural sense; but it enlightens the spiritual man, as the sun's light does the eye; but the natural man, as the light of the moon and stars enlighten his eye. Everyone is enlightened according to the spiritual affection of truth and good, and at the same time according to genuine truths, by which he has opened his rational faculty.
 The same is meant by "day" and "night," in the following passages:
And God said, Let there be luminaries in the expanse of the heavens to distinguish between the day and the night; and God made two great luminaries, the great luminary to rule in the day, and the lesser luminary to rule in the night; and the stars: And God set them in the expanse of the heavens to give light upon the earth, and to rule in the day and in the night, and to distinguish between the light and the darkness (Gen. 1:14-19).
Jehovah made great luminaries, the sun to rule in the day, the moon and stars to rule in the night (Ps. 136:7-9).
To Thee, O Jehovah, is the day, and to Thee the night; Thou hast prepared the light and the sun (Ps. 74:16).
Jehovah that giveth the sun for the light of the day, the statutes of the moon and stars for the light of the night (Jer. 31:35).
If ye can make void My covenant of the day and My covenant of the night, that there should not be day and night in their season, My covenant also with David My servant shall be made void; if I have not set My covenant of the day and of the night, the statutes of heaven and earth, I will also reject the seed of Jacob and of David (Jer. 33:20-21, 25-26).
These are adduced, that it may be known that the darkening of both kinds of light is meant.
