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 Jehovah will be for you an everlasting light; your sun will no more go down nor your moon be withdrawn, for Jehovah will be for you an everlasting light.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.

Footnotes:

487. 'Days means periods of time and states in general. This has been shown in Chapter 1, where the 'days of creation' have no other meaning. In the Word it is very common for a whole period of time to be called 'a day', as it clearly is in the present verse and in verses 5, 8, 11, 14, 17, 20, 23, 27, 31, below; and therefore the states that belong to periods of time in general are meant by 'days' as well. And when 'years' is attached, then periods of years mean the natures of those states, and so the states in particular.

[2] The most ancient people had their own particular numbers which they would use to mean different aspects of the Church - for instance, the numbers three, seven, ten, twelve, and many which they obtained from these and other numbers - and in so doing incorporated states of the Church. These numbers therefore contain arcana that would require considerable effort to unravel. Really a number was an evaluation of the states of the Church. The same feature occurs throughout the Word, especially in the prophetical. And the religious ceremonies of the Jewish Church also entail numbers specifying periods of time as well as quantities; for example, in connection with sacrifices, minchahs, oblations, and other practices, which in every case have special reference to holy things. Consequently eight hundred in this verse, nine hundred and thirty in the next, and the numbers of years mentioned in the verses that follow after that, embody in particular more matters than can possibly be retold; matters, that is to say, which have to do with changes in the state of their Church in relationship to their own general state. Later on, in the Lord's Divine mercy, the meaning of the simple numbers up to twelve will be given, for without knowing these first of all no one can grasp what compound numbers mean.
