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 Jehovah will be for you an everlasting light; your sun will no more go down nor your moon be withdrawn, for Jehovah will be for you an everlasting light.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

6256. 'And the eyes of Israel were weak' means his obscurity of discernment. This is clear from the meaning of 'the eyes' as the sight of the understanding, dealt with in 2701, 4087, 4379, 4403-4421, also meant by 'seeing', as above in 6249; from the representation of 'Israel' as spiritual good within the natural, dealt with above in 6253; and from the meaning of 'being weak', when used in reference to the eyes, as obscurity, thus obscurity of discernment. The reason Why Israel's discernment had become obscure when he blessed Joseph's sons was that he had reached the final phase of his representation, though a more general reason is that an obscurity of perception exists in the spiritual good which 'Israel' represents; for that good comes from the natural, in which inferior natural light predominates, not superior heavenly light in which spiritual and celestial good from the rational dwells. Such is the nature of the external man, also called the natural man. When the expression 'spiritual good from the natural' is used, people whose good is such are meant. They are those who belong to the Lord's spiritual Church, which also is why 'Israel' represents that Church, 4286; and compared with celestial people, members of that Church, who are spiritual people, live in obscurity, see 2708, 2715, 2716, 2718, 2831, 2849, 2935, 2937, 3246, 4402. And since they live in obscurity they also put the truth of faith in the first place, even as Israel did here, in that he made Ephraim take precedence over Manasseh.

[2] The reason why spiritual people believe that the truth of faith takes precedence is that it is by means of truth that they are led on to good, 2954; and while they are being led to it they have no perception of good because good flows from within into an affection for truth, and so does not enter their discernment until they have been regenerated. This also explains why they call the good deeds of charity the fruits of faith, though little concern is shown for such fruits by those who suppose that faith alone without good works saves a person, even in the final hour when he dies, irrespective of the life he had led before that. This way of thinking is clearly an obscurity of discernment regarding goodness and truth. But be that as it may, those who make faith take precedence over charity on doctrinal grounds and yet lead a charitable life are people who belong to the Lord's spiritual Church and are saved. For in life they make the good of charity take precedence, but in doctrine the truth of faith.
