1837. That 'as the sun was going down' means the period of time and the state just before the close is clear from the meaning of 'the sun'. In the internal sense 'the sun' means the Lord, and because of this means the celestial things of love and charity, consequently love and charity themselves, dealt with already in 30-38, and 1053. From this it is evident that 'the going down of the sun' is the last period of time in the Church, which is called the close, when charity does not exist any longer. The Lord's Church is also compared to the times of day, its earliest time being compared to sunrise, or dawn and morning, and its final period to sundown, or evening and the shadows that fall then; for there is indeed a similarity between the two. In like manner the Church is compared to the seasons of the year, its earliest time being compared to spring when everything is flowering, while the time next to the last is compared to autumn when everything starts to die off. Indeed, the Church is also compared to metals, its first time being called golden, its last that of iron and clay, as in Daniel 2:31-33. These considerations show what is meant by 'as the sun was going down', namely that the period of time and the state just before the close are meant, for the sun had not yet gone down. In what follows the subject is the state of the Church when the sun had gone down, at which point thick darkness descended, and a smoking furnace and a flaming torch passed between the pieces.

1053. That 'and the bow will be in the cloud' means the state of that man is clear from what has been stated and shown already about the bow in the cloud, that is to say, in the next life a person or soul is known among angels from his sphere; and as often as it pleases the Lord that sphere is represented by means of colours like those of the rainbow, variously according to each person's state as to faith in the Lord and thus respectively as to goods and truths of faith. In the next life colours present themselves to view, which on account of their brilliance and splendour are immensely superior in beauty to colours seen with the eyes on earth. Each colour represents something celestial or spiritual.

[2] Those colours derive from the light in heaven, and from the variegation of spiritual light, as stated above. Indeed angels live in light so bright that the light of the world is in comparison no light at all. The light of heaven in which angels live, compared with the light of the world, is as the light of the sun at midday to the light of a candle that is put out and ceases to give any light at all when the sun rises. In heaven there is celestial light and there is spiritual light. Let me compare the two by saying that celestial light is as the light of the sun, while spiritual light is as the light of the moon. But all manner of variation exists depending on the state of the angel receiving the light. The same applies to colours since they are a product of the light. In the heaven of celestial angels the Lord Himself is the Sun, and in the heaven of spiritual angels the Moon. To people who have no conception of the life which souls lead after death these matters are unbelievable. They are nevertheless completely true.
