28. The first-born from the dead. That this signifies from whom is all good in heaven, is evident from the signification of first-born, when said of the Lord, as denoting the Divine good in heaven, thus all good there. The reason why this is signified by first-born, is, because by generations, in general and in particular, are signified spiritual generations, which are those of good and truth, or of love and faith. Therefore, by father, mother, sons, daughters, sons-in-law, daughters-in-law, and sons' sons, are signified the goods and truths which generate, and which are generated, in their order (Arcana Coelestia 10490). For in heaven there are no other nativities; and, this being the case, by first-born is not meant first-born, but the good of heaven and the church, because this is in the chief place. Now, because all good in heaven exists from the Lord, therefore He is called the First-born.

[2] The reason why He is called the first-born from the dead, is because, when He rose from the dead, He made His Human Divine Good by union with the Divine which was in Him from conception. This is why He is called the first-born from the dead; and why He says of Himself in David,

"I will make him the first-born, higher than the kings of the earth" (Psalm 89:27).

What is meant by His being higher than the kings of the earth, will be seen in the subsequent article. (That the Lord, when He departed out of the world, made His Human Divine Good, may be seen, Arcana Coelestia 3194, 3210, 6864, 7499, 8724, 9199, 10076, thus that He came forth from the Father and returned to the Father, n. 3194, 3210; and that after the union, the Divine truth, which is the Comforter, the Spirit of truth, goes forth from Him, n. 3704, 3712, 3969, 4577, 5704, 7499, 8127, 8241, 9199, 9398, 9407. But this mystery may be seen more fully explained in the small work, The Doctrine of the New Jerusalem 293-295; and in the passages from Arcana Coelestia there cited, n. 303-305.)

Since the Lord as to His Divine Human is called the first-born, because all good goes forth from Him, therefore all the first-born in the Israelitish church were holy to Jehovah; and therefore also the Levites were taken in the place of all the first-born in Israel. For by the sons of Levi were represented those of the church who are in the good of charity. On this account, also, a double portion of the inheritance fell to the first-born. All this, because the first-born signified good from the Lord, and, in the highest sense, the Lord Himself as to the Divine Human, from which all good comes; for all the things commanded in the Israelitish church were representative of spiritual and celestial Divine things.

[3] That all the first-born in the Israelitish church were holy to Jehovah is evident from Moses, in the following passages:

"Sanctify unto me all the first-born, whatsoever openeth the womb among the sons of Israel, in man and in beast; it is mine" (Exodus 13:2).

"Thou shalt cause to pass over unto Jehovah all that openeth the womb, and every firstling that cometh of a beast as many as thou hast, the males shall be Jehovah's" (13:12).

"Thou shalt not delay the first fruits of thy produce, and the first fruits of thy wine; the first-born of thy sons shalt thou give unto me. Likewise shalt thou do with thine oxen and with thy sheep; seven days it shall be with its dam; on the eighth day thou shalt give it me. And ye shall be men of holiness unto me" (Exodus 22:29-31).

The reason why they were to give also the first-born of beasts, was, because these also were representative; on which account, also, they were made use of in burnt-offerings and sacrifices. (What the various beasts in these services represented, may be seen, Arcana Coelestia 1823, 3519, 9280, 10042.) The Levites were accepted in place of all the first-born in Israel (concerning which, see Numbers 3:12, 13, 41, 45; 8:15-19), because, as observed above, the sons of Levi represented, and thence signified, the good of charity, and Levi, in the highest sense, represented the Lord as to that good (as may be seen, n. 3875, 3877, 4497, 4502, 4503, 10017). The reason why a double portion of the inheritance fell to the first-born (Deuteronomy 21:17), was, because a double portion signified the good of love (n. 720, 1686, 5194, 8423).

10017. 'And the priesthood shall be theirs' means the stages, following one after another, of the Lord's work of salvation. This is clear from the meaning of 'the priesthood' or 'the priestly office' as that which is representative of the Lord's whole work of salvation, dealt with in 9809. The reason why the stages following one after another is meant is that the priesthood of Aaron's sons is the subject here, and his sons represent the things which emanate and so follow in order one after another, 9807. The situation in all this is that the priesthood which Aaron represents consists in the work of saving those who are in the Lord's celestial kingdom, this kingdom being the proper meaning in the Word of 'a kingdom of priests'. But the priesthood which Aaron's sons represent consists in the work of saving those who are in the Lord's spiritual kingdom emanating directly from His celestial kingdom. From this it is evident that 'the priesthood' is used in the present instance to mean the stages, following one after another, of the Lord's work of salvation. But the priesthood which the Levites represent consists in the Lord's work of salvation at a further stage.

[2] There are three realities which follow one another in order. These are the celestial, which is the good of love to the Lord; the spiritual, which is the good of charity towards the neighbour; and the natural springing from these, which is the good of faith. Since these three are realities which follow one another in order there are also three heavens, and in them the types of good follow in that order. The work of saving those with whom celestial good exists is represented by Aaron's priesthood; but the work of saving those with whom spiritual good exists is represented by the priesthood of Aaron's sons, and the work of saving those with whom the natural good springing from these exists is represented by the priesthood of the Levites. And since the things following one another in order emanate from the good of love to the Lord, which is represented by Aaron and his priesthood, it is said of the Levites that they were given to Aaron. For things which emanate belong to that from which they emanate; such emanations or stages following one after another owe their very existence to that source, as accords with what has been stated a little above in 10011. The fact that the Levites were given to Aaron and his sons to perform priestly duties under them, see Numbers 3:1-end.
