31. That 'the great lights' mean love and faith, and are also mentioned as the sun, the moon, and the stars, is clear from various places in the Prophets, as in Ezekiel,

When I have blotted you out, I will cover the heavens and darken their stars, I will cover the sun with a cloud, and the moon will not give its light. All the bright lights in the heavens I will make dark over you, and I will put darkness over your land. Ezekiel 32:7-8.

This refers to Pharaoh and the Egyptians, who are used in the Word to mean the sensory and the factual. The meaning here is that they will have blotted out love and faith by means of sensory evidence and factual knowledge. In Isaiah,

The day of Jehovah for making the earth a desolation; for the stars of the heavens and their constellations ¹ will not give their light; the sun will be darkened in its rising, and the moon will not shed its light. Isaiah 13:9-10.

In Joel,

The day of Jehovah is coming, a day of darkness and thick darkness. The earth quakes before Him, the heavens tremble, the sun and moon are darkened, and the stars withdraw their shining. Joel 2:10.

[2] In Isaiah, in reference to the Lord's Coming and the enlightenment of gentiles, and so to a new Church, in particular to individuals who are in darkness but who are beginning to receive the light and be regenerated,

Arise, shine, for your light has come. Behold, darkness is covering the earth, and thick darkness the peoples, but Jehovah will arise upon you, and nations will walk towards your light, and kings to the brightness of your rising. Jehovah will be for you an everlasting light; your sun will no more go down nor your moon be withdrawn, for Jehovah will be for you an everlasting light. Isaiah 60:1-3, 19-20.

In David,

Jehovah makes the heavens by intelligence, He spreads out the earth upon the waters, He makes the great lights, the sun to have dominion over the day, and the moon and stars to have dominion over the night. Psalms 136:5-9.

And in the same author,

Praise Jehovah, sun and moon, praise Him, all stars of light! Praise Him, heaven of heavens, and waters that are above the heavens! Psalms 148:3-4.

[3] In all of these places 'the lights' mean love and faith. Because the lights represented and meant love and faith in the Lord, the Jewish Church was commanded to keep a light burning all the time from evening till morning, for every command which that Church received was representative of the Lord. Concerning this light it is said,

Command the sons of Israel that they take oil for the light, to cause a lamp to burn continually. In the Tent of Meeting outside the veil which is before the testimony Aaron and his sons shall tend it from evening to morning before Jehovah. [Exodus 27:20-21]

That this means the love and faith which the Lord kindles and causes to shine in the internal man, and by means of the internal man in the external man, will in the Lord's Divine mercy be shown at that point in Exodus.

V:

3498. 'I do not know the day of my death' means the life within the natural. This is clear from the meaning of 'day' as state, dealt with in 23, 487, 488, 493, 893, 2788, and from the meaning of 'death' as rising again or awakening into life, dealt with in 3326. 'The day of death' accordingly means a state of awakening to life, or what amounts to the same, it means life - the life within the natural, it is evident, being meant in particular here, because that life is the subject here. What is implied in all this does not become clear unless one knows about the life of the rational, and the life of the natural, or what amounts to the same, about the life of the internal man and the life of the external man. The life of the rational or internal man is distinct and separate from that of the natural or external man, so distinct indeed that the life of the rational or internal man may exist quite independently of the life of the natural or external man; but the life of the natural or external man cannot exist apart from that of the rational or internal man. For the external man lives from the internal man, so much so that if the life of the internal man ceased to be, the life of the external man would instantly be no more. Exterior things are accordingly dependent on interior in the way that things which are posterior exist from those that are prior, or as an effect exists from its efficient cause. For if the efficient cause ceased to be, the effect would instantly be no more. The same is also so with the life of the external man in relation to the life of the internal man.

[2] This may be seen even more clearly in the human being, for while a person is in the world, that is, while he lives in the body, his rational is distinct and separate from the natural, so much so that he can be raised above the level of external sensory perceptions which belong to the body, and even to a certain extent above the level of inner sensory perceptions which belong to his natural man, and to be aware on the level of his rational, and so of spiritual thought. This is even more evident from the fact that when a person dies he leaves behind him altogether the external sensory perceptions that belong to the body, retaining at the same time the life of his interior man. Indeed he brings with him even the facts that exist in the external or natural memory, though he does not have the use of them, see 2475-2477, 2479-2483, 2485, 2486. From this it is evident that the rational or internal man is distinct and separate from the external man. But while a person is living in the body his rational does not seem to be distinct and separate from the natural, the reason being that he is living in the world or the natural order. That being so the life of the rational manifests itself within the natural, so much so that the rational does not seem to have any life at all if the natural does not at the same time have any. The amount of life that the rational seems to have in this case depends on how far the natural corresponds to it - see above in 3493. From this it may be seen that there is a corresponding life in the natural, which life is meant by the words which Isaac addressed to Esau, 'I do not know the day of my death'. For 'Isaac' represents the rational, and 'Esau' the natural, in both cases as regards good.
