664. And after three days and a half.- That this signifies when completed, thus the end of the old church, and the beginning of a new church, is evident from the signification of three days and a half, as denoting fulness or completion at the end of the old church, when there is the beginning of a new church, concerning which see above (n. 658). The reason why it is said, after three days and a half, is, that days, in the Word, signify states, here, the last state of the church. For all times, in the Word, as hours, days, weeks, months, years, and ages, signify states in the Word, as in this case, the last state of the church, when there is no longer any good of love or truth of faith remaining. Because days signify states, and since in the first chapter of Genesis the establishment of the Most Ancient Church is treated of which was accomplished successively from one state to another, therefore it is said there that there was evening and there was morning the first, the second, the third, the fourth, the fifth, and sixth days, unto the seventh, when it was completed (Genesis 1:5, 8, 13, 19, 23, 31), and the days there do not mean days, but the successive states of the regeneration of men at that time, and the consequent establishment of the church with them. So also elsewhere in the Word.

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.
