In a general sense, being "born" in the Bible represents one spiritual state producing another, usually some form of love or affection producing or "giving birth" to truth or to desires for good. This is not hard to see: If you love someone, that love naturally gives birth to ideas on how to be good to that person and make him or her happy. This is why sons and daughters in the Bible represent true ideas and desires for good. On a higher level, though, being born represents what the Writings call "regeneration," or the life-long process of putting off our natural thoughts and desires and embracing spiritual life from the Lord. This is what the Bible means when it talks about being "born again" – if we live our lives from the Lord, He will eventually take away our evil desires so that we can be "born" as angels in heaven, free of evil desires and dark thoughts. Of course, these two levels of meaning are really one: The Lord is love itself, and if we align with Him we become forms of love and truth ourselves, expressions of His love just as the desire to do something good might be the expression of your love for a friend.

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).

5194. 'And it happened at the end of two years of days' means after the state when the joining together took place, that is to say, when the powers of the senses belonging to the exterior natural and those belonging to the interior natural were joined together, both of which powers are dealt with in the previous chapter. This is clear from the meaning of 'two years of days', that is, a period of two years, as a state involving a joining together; for 'two' means a joining together, 1686, 3519, while 'years' means states, as does 'days'. For the meaning of years' as states, see 487, 488, 493, 893, and for that of 'days', 27, 487, 488, 497, 2788, 3462, 3785, 4850. The reason 'two' means a joining together is that every single thing in the spiritual world, and consequently in the natural world, has two forces associated with it - goodness and truth. Good is an active inflowing force, truth a passive, recipient one. Also, because everything has these two forces associated with it, and because nothing can ever be brought forth unless the two are made one by becoming so to speak married to each other, a joining together is therefore meant by them.

[2] This type of marriage exists in every single thing within the natural order and its three kingdoms; without it nothing whatever can come into existence. For anything to come into existence within the natural order there needs to be heat and light, heat in the natural world corresponding to the good of love in the spiritual world, and light corresponding to the truth of faith. These two - heat and light - must act as one if anything is to be brought forth. If they do not act as one, as is the case in winter-time, nothing at all is brought forth. The same holds true on a spiritual level, as is quite evident with the human being, who has two mental powers - will and understanding. The will has been formed so that it may receive spiritual heat, that is, the good of love and charity, while the understanding has been formed so that it may receive spiritual light, that is, the truth of faith. Unless these two residing with a person make one nothing is brought forth, for the good of love devoid of the truth of faith cannot give definition and particular character to anything, while the truth of faith devoid of the good of love cannot bring anything into effect. So that the heavenly marriage may exist in a person therefore, or rather so that a person may be in the heavenly marriage, those two entities must make one in him. This explains why the ancients likened every single thing in the world, and every single thing within the human being, to a marriage, 54, 55, 568, 718, 747, 917, 1432, 2173, 2516, 2731, 2739, 2758, 3132, 4434, 4875, 5138. From all this one may see why it is that 'two' means a joining together.
