269. And a rainbow was round about the throne in aspect like an emerald, signifies the appearance of Divine truth in the heavens about the Lord. This is evident from the signification of "a rainbow in aspect like an emerald," as denoting the appearance of Divine truth in its circumference; for "a rainbow round about the throne" signifies Divine truth round about; "in aspect like" signifies appearance. The appearance was like an emerald, because it had reference to the Last Judgment; for the color of this stone is green, and "green" signifies truth obscured. Divine truth in its brightness appears either of the color of heaven, or in various colors in beautiful order like a rainbow; but when obscured it appears of the color of an emerald. The heaven that was obscured was the heaven called "the former heaven," on which judgment was to be executed, and which was about to perish (See Revelation 21:1). On this account "a rainbow round about like an emerald" is mentioned. "Rainbow" signifies Divine truth in the heavens in its order and consequently in its beauty, because there are infinite varieties of truth from good in the heavens, and when these are represented by colors, they present the aspect of a most beautiful rainbow. For this reason "a rainbow" was made the sign of the covenant after the flood (Genesis 9:12-17). (That there are infinite varieties in the heavens see in the work on Heaven and Hell 56, 405, 418, 486; and in the small work onThe Last Judgment 13; and in Arcana Coelestia 684, 690, 3744, 5598, 7236, 7833, 7836, 9002; that colors in heaven appear from the light there, and that they are modifications and variegations of the light, n. 1042, 1043, 1053, 1624, 3993, 4530, 4742, 4922; and that the colors appear various according to the varieties of the states of truth from good, and thence of intelligence and wisdom, n. 4530, 4677, 4922, 9466; that rainbows are seen in heaven, and whence and what they are, n. 1042, 1043, 1623-1625)

7236. 'According to their armies' means in accordance with the genera and species of good within truths. This is clear from the meaning of 'an army' as the truths that constitute faith, dealt with in 3448. But forms of good in the spiritual Church are essentially nothing other than truths, since truths are called forms of good when people lead their lives in accordance with those truths. When therefore the word 'army' is used to refer to those within the spiritual Church who have been regenerated, forms of the good of truth or forms of good within truths are meant. The reason why it says that the children of Israel were to be led out 'according to their armies' is that it is speaking about the time when they will come out of Egypt - in the internal sense when they will come out of conflicts with falsities, thus after they have performed spiritual military service. The proper way to understand the command that they were to be led out 'according to their armies' is that they were to be distinguished in keeping with forms of good within truths, thus were to be divided into groups according to different kinds of good. And this was done in order that they might represent the Lord's kingdom in the heavens. There all have been divided up and allotted a place in the Grand Man in accordance with both the genus and the species of each one's good.

[2] The fact that all in heaven are divided up in accordance with their different kinds of good shows how manifold and how varied good is; it is so varied that good is never the same with one person as it is with another. Indeed if millions of people went on being multiplied forever, one person's good would still not be like another's, just as one person's face is not like another's; and in heaven furthermore good is what shapes angels' faces. The reason for the unending variety is that every form has distinct and varied constituent parts; for if two were exactly alike they could not be two but a single unit. This also explains why in the natural order no one thing ever exists which is like another in every respect.

[3] What makes good so varied is truth; when this is joined to good it gives the good specific character. One reason why truth is so manifold and varied that it can make good so greatly varied is that truths are countless, and interior truths take on a different form from exterior ones. Another reason is that false impressions gained by the outward senses attach themselves, and also false ideas that are products of evil desires. Since therefore truths are so countless one can see that when they are joined to good just as many variations are produced, so many that one form of good can never be the same as another. This is plain to anyone who knows that from merely twenty-three letters joined together in different combinations the words contained in all languages can be produced; indeed even if there were thousands of languages, an unending variety of combinations could be produced. So what will be the product of varieties numbering thousands and millions, as truths do? Confirmation of the existence of those varieties is also contained in the proverb in general use in the world that there are as many opinions as there are heads, that is, ideas are as varied as the number of people there are.
