28. The Firstborn from the dead, signifies from whom is all good in heaven. This is evident from the signification of the "firstborn," as being, in reference to the Lord, Divine good in heaven, thus all good there. The "firstborn" signifies this, because by generations, in general and in particular, spiritual generations are signified, which are the generations of good and truth or of love and faith; from this it is, that by "father," "mother," "sons," "daughters," "sons-in-law," "daughters-in-law," and "son's sons," are signified goods and truths which generate and are generated in their order (Arcana Coelestia 10490), for in heaven there are no other nativities. This being so, by "firstborn" is not meant the firstborn, but the good of heaven and of the church, because this is in the first place. And since it is the Lord from whom all good in heaven is, He is called the "Firstborn." He is called "the Firstborn from the dead," because, when He arose from the dead, He made His Human to be Divine good by union with the Divine that was in Him from conception.

[2] This is why He is called "the Firstborn from the dead," and says of Himself in David:

I will make Him the Firstborn, high above the kings of the earth (Psalms 89:27).

What is meant by His being "high above the kings of the earth" will be seen in a subsequent article.

(That the Lord, when He departed from the world, made His Human Divine good, see 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, proceeds from Him, n. 3704, 3712, 3969, 4577, 5704, 7499, 8127, 8241, 9199, 9398, 9407. But this arcanum may be seen more fully explained in the small work on The Doctrine of the New Jerusalem 293-295; and in the passages there cited from the Arcana Coelestia 303-305.)

As the Lord in respect to the Divine Human is called "the Firstborn," for the reason that all good proceeds from Him, so all the firstborn in the Israelitish church were holy to Jehovah; so also the Levites were received in place of all the firstborn in Israel; for by the sons of Levi were represented those of the church who are in the good of charity: therefore also a double portion of inheritance was allotted to the firstborn; all this for the reason that the firstborn signified the good that is from the Lord, and in the highest sense, the Lord Himself in respect to the Divine Human from which is all good. For all things that were commanded in the Israelitish church were representative of Divine things, spiritual and celestial.

[3] That all the firstborn in the Israelitish church were holy to Jehovah appears from Moses, in the following passages:

Sanctify unto Me all the firstborn, whatsoever openeth the womb among the sons of Israel, both of man and of 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 (Exodus 13:12).

Thou shalt not delay to offer the firstfruits of thy produce, and the firstfruits of thy wine. The firstborn 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).

They were to give also the firstborn of beasts, because these, too, were representative; and because they represented they were also made use of in burnt-offerings and sacrifices.

(What the various beasts in these services represented, see Arcana Coelestia 1823, 3519, 9280, 9980, 10042. Why the Levites were accepted in place of all the firstborn in Israel, see Numbers 3:12, 13, 41, 45; 8:15-20, was, as was said above, because the "sons of Levi" represented, and therefore signified, the good of charity, and "Levi," in the highest sense, signified the Lord as to that good, see Arcana Coelestia 3875, 3877, 4497, 4502, 4503, 10017. A double portion of the inheritance was given to the firstborn, Deuteronomy 21:17, because a "double portion" signified the good of love, Arcana Coelestia 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.
