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 Jehovah will be for you an everlasting light; your sun will no more go down nor your moon be withdrawn, for Jehovah will be for you an everlasting light.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

5402. 'That there was corn in Egypt' means the intention to acquire truths to itself through factual knowledge, which is 'Egypt'. This is clear from the meaning of 'corn' as the truths known to the Church, or the truths of faith - 'an abundance of corn' being a multiplication of truth, see 5276, 5280, 5292; and from the meaning of 'Egypt' as factual knowledge, dealt with in 1164, 1165, 1186, 1462, and, in the genuine sense, facts known to the Church, see 4749, 4964, 4966. As is evident from the words that come immediately after them, the ones used here imply an intention to acquire these truths to itself. The expression 'facts known to the Church', which 'Egypt' stands for here, is used to mean all the cognitions of truth and good before they become linked to the interior man, that is, through the interior man to heaven, and thus through heaven to the Lord. The teachings of the Church and its religious observances, in addition to its cognitions about why and how these represent spiritual realities and the like, all exist as nothing more than known facts until a person sees from the Word whether they are truths, and having done so makes them his own.

[2] There are two ways of acquiring the truths of faith, one way being through religious teaching, the other through the Word. When religious teaching alone is the way by which a person acquires them, he pins his faith on those who have deduced such truths from the Word, and assures himself that they are indeed truths because others have said that they are. Thus he does not believe those truths on account of any faith of his own but on account of that possessed by others. When however he gathers those truths for himself from the Word and assures himself for that reason that they are truths, he believes them on account of their Divine origin and so on account of a faith received from the Divine. Initially everyone within the Church acquires the truths that constitute faith from religious teaching; indeed this is how he ought to acquire them because he is not as yet equipped with judgement of his own that will enable him to see those truths from the Word. At this time those truths are for him no different from factual knowledge. But once he does possess the judgement to see them on his own, and if he does not consult the Word to the end that he may see from there whether they are indeed truths, they remain with him as factual knowledge. If however he does consult the Word with an affection for and an intention to know truths, and having found them there acquires them from their own true source, he receives the truths of faith from the Divine and makes them his own. These and other matters like them are what the internal sense is dealing with here; for 'Egypt' is that factual knowledge, while 'Joseph' is truth received from the Divine and so truth obtained from the Word.
