6417. 'The son of a fertile one is Joseph' means the spiritual Church, in the highest sense the Lord's Divine spiritual. This is clear from the representation of 'Joseph' in the highest sense as the Lord's Divine spiritual, in the internal sense as the spiritual kingdom and the good of faith, and in the external sense as fruitfulness and multiplication, dealt with in 3969, 3971; and since 'Joseph' is the fruitfulness of good and the multiplication of truth, he is called 'the son of a fertile one'. 'Joseph' is used here to refer to the Lord's spiritual kingdom, while above 'Judah' is used to refer to His celestial kingdom; for there are two kingdoms constituting heaven, the celestial and the spiritual. The celestial kingdom constitutes the inmost or third heaven, the spiritual kingdom the middle or second heaven; and the Lord is seen by the spiritual kingdom as the moon, but by the celestial kingdom as the sun, 1053, 1521, 1529-1531, 4060. When one says that 'Joseph' in the highest sense represents the Lord's Divine Spiritual, the following is involved: The Lord is nothing else than Divine Good. What goes forth from His Divine Good and flows into heaven is in His celestial kingdom called the Divine celestial, but in His spiritual kingdom the Divine spiritual, so that one uses the expression Divine spiritual or Divine celestial with reference to receptivity.

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.
