269. And there was a rainbow round about the throne in aspect like unto an emerald. That this signifies the appearance of Divine truth in the heavens surrounding the Lord is evident from the signification of a rainbow in aspect like unto an emerald, as denoting the appearance of Divine truth in its circumference; for a rainbow round about the throne signifies Divine truth around it, and in aspect signifies appearance. The reason why the appearance of the rainbow was like that of an emerald, is that it indicated the Last Judgment, for the colour of this stone is green, and green signifies truth obscured. Divine truth in its splendour appears either of a sky-colour, or of various colours disposed in beautiful order, as those of the rainbow; but when it is obscured it appears of the colour of an emerald. The heaven which is called the former heaven was that on which judgment was to be executed, and which was about to perish (see Apoc. 21:1) which caused the obscurity. This is why mention is made of a rainbow, and its aspect like that of an emerald. The reason why the rainbow signifies Divine truth in the heavens in its order, and thence in its beauty, is that there are infinite varieties of truth from good in the heavens; and when they are represented by colours, they present the appearance of a beautiful rainbow. This is why the rainbow was made a sign of the covenant after the flood (Genesis 9:12-17). (That there are infinite varieties in the heavens may be seen in the work, Heaven and Hell 56, 405, 418, 486, and in the small work, The Last Judgment 13; and in Arcana Coelestia 684, 690, 3744, 5598, 7236, 7833, 7836, 9002. That colours in heaven appear from the light there, and that they are its modifications and variegations, n. 1042, 1043, 1053, 1624, 3993, 4530, 4742, 4922; and that the colours 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 appear in heaven, and whence and what they are, n. 1042, 1043, 1623, 1624, 1625.)

7833. 'According to the household of his fathers, a member of the flock according to the household' means according to each one's specific kind of good. This is clear from the meaning of 'household of fathers' as one family's good, distinct from another's good; for 'a father's house' means a person in respect of internal good, 3128. The implications of this are as follows: All the tribes of Israel mean all forms of the truth and good of faith and charity in their entirety, each tribe meaning one general kind of good or of truth, see 3858, 3926, 3939, 4060, 6375, 6377, 6640. Thus every separate family within a tribe meant a specific kind of good, and therefore the good of one specifically, distinct from another's good. But the household of the fathers within a family meant an individual type belonging to one specific kind. The reason why all these kinds of good were meant by the tribes, families, and households into which the children of Israel were divided was in order that they might represent heaven; for the varieties of good there are divided into general, specific, and individual. And these determine the ways in which angels are linked to one another. It should be recognized that one person's good is never exactly the same as another's good. Rather, they are varied, so varied that they can be distinguished into higher overall categories, and these into lower sub-divisions, down to particular and most particular kinds. Regarding forms of the good of love and faith, that they are so varied, see 684, 690, 3241, 3267, 3744-3746, 3986, 4005, 4149, 5598, 7236. From this it may now be evident why they were commanded to take for themselves each one a member of the flock according to the household of his fathers, a member according to the household.
