3084. 'And went up' means a raising up. This is clear from the meaning of 'going up' as being raised up. The expression 'raised up' is used to describe from what is lower to what is higher, and because it is used to describe this it is also used to describe from what is exterior to what is interior, for the two are one and the same. Indeed what is lower and higher in human thought is exterior and interior in angelic thought, as with the idea of heaven. By men heaven is seen as that which is higher, but by angels as that which is interior. It is similarly so with the natural with man. In relation to his spiritual it is exterior, while the spiritual in turn is exterior in relation to the celestial. Or what amounts to the same, factual knowledge which belongs to the natural man is exterior in relation to truth, while truth is exterior in relation to good. Therefore also factual knowledge in relation to truth is called a covering as well as a garment, and so in a similar way is truth in relation to good.

[2] This explains why the expressions 'going up' to Jerusalem, but 'coming down' from Jerusalem are used; also 'going up' from Jerusalem to Zion, and 'coming down' from Zion to Jerusalem; for the parts surrounding Jerusalem mean the exterior features of the Church, Jerusalem meaning the more interior features and Zion the inmost. Since in the internal sense this verse describes the initial stage in the raising up of truth from the natural man to the rational man, therefore it is first of all said here that the affection for truth represented by Rebekah 'went down to the spring' and shortly after that 'went up'. For as stated above in 3074, Divine love flows into the affection for good, and from there into the affection for truth, and in so doing brings life and light to the things that are in the natural man, and at the same time orders them. This is the meaning of 'going down'. In this way truths are raised up from the natural man into the rational man where they are joined to good. This is the meaning of 'going up'.

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.
