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 Jehovah will be for you an everlasting light; your sun will no more go down nor your moon be withdrawn, for Jehovah will be for you an everlasting light.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

The number "two" has two different meanings in the Bible. In most cases "two" indicates a joining together or unification. This is easy to see if we consider the conflicts we tend to have between our "hearts" and our "heads" -- between what we want and what we know. Our "hearts" tell us that we want pie with ice cream for dinner; our "heads" tell us we should have grilled chicken and salad. If we can bring those two together and actually want what's good for us, we'll be pretty happy. We're built that way -- with our emotions balanced against our intellect -- because the Lord is built that way. His essence is love itself, or Divine Love, the source of all caring, emotion and energy. It is expressed as Divine Wisdom, which gives form to that love and puts it to work, and is the source of all knowledge and reasoning. In His case the two aspects are always in conjunction, always in harmony. It's easy also to see how that duality is reflected throughout creation: plants and animals, food and drink, silver and gold. Most importantly, it's reflected in the two genders, with women representing love and men representing wisdom. That's the underlying reason why conjunction in marriage is such a holy thing. So when "two" is used in the Bible to indicate some sort of pairing or unity, it means a joining together. In rare cases, however, "two" is used more purely as a number. In these cases it stands for a profane or unholy state that comes before a holy one. This is because "three" represents a state of holiness and completion (Jesus, for instance, rose from the tomb on the third day), and "two" represents the state just before it.
