6027. 'And he sent Judah before him to Joseph' means a communication of the good of the Church with the internal celestial. This is clear from the representation of 'Judah' as the good of the Church, dealt with in 5583, 5603, 5782, 5794, 5837; and from the representation of' Joseph' as the internal celestial, dealt with in 5869, 5877. And 'sending before him', it is self-evident, means communicating. The reason why Judah and not anyone else was sent was so that a direct communication of good with good might be denoted, that is, a direct communication of external good, which 'Judah' represents, with internal good, which 'Joseph' represents. For good that is the good of love to the Lord and charity towards the neighbour flows in from Him by way of the internal into the external, the amount of good in the external determining how much is received there. But if merely the truth of faith and no good is present in a person's external, the inflow of good from the Lord by way of the internal cannot be received in the external. For no direct communication with truth can exist there, only an indirect one through good. This is why Judah and not anyone else was sent from Jacob to Joseph.

1589. 'Like the land of Egypt as you come to Zoar' means facts acquired from affections for good. This becomes clear from the meaning of 'Egypt', dealt with in 1164, 1165, in a good sense in 1462, as knowledge, and from the meaning of 'Zoar' as the affection for good. Zoar was a city not far from Sodom, to which also Lot fled when he was snatched by angels from the fire of Sodom, as described in Genesis 19:20, 22, 30. In addition to this, Zoar is referred to in Genesis 14:2, 8; Deuteronomy 34:3; Isaiah 15:5; Jeremiah 48:34, in all of which places also it means an affection. And since it means the affection for good, it also means in the contrary sense, as is usual, the affection for evil.

[2] There are three constituent parts of the external man - rational, factual, and external sensory. The rational part is more interior, the factual more exterior, and the external sensory the most external. The rational is the part by means of which the internal man is joined to the external, the character of the rational determining the character of this conjunction. The external sensory part consists in the present instance in sight and hearing. But in itself the rational has no existence if affection does not flow into it, making it active so as to receive life. Consequently the rational receives its character from that of the affection flowing into it. When the affection for good flows in, that affection for good becomes with the rational an affection for truth; and the contrary happens when the affection for evil flows in. Because the factual part attaches itself to the rational and serves as its agent it also follows that the affection flows into and reorganizes the factual part. For nothing has life in the external man apart from affection. The reason is that the affection for good comes down from the celestial, that is, from celestial love, which imparts life to everything into which it flows, even to affections for evil, that is, to evil desires.

[3] Actually the good of love from the Lord flows in constantly, doing so through the internal man into the external. But anyone who is governed by an affection for evil, that is, by an evil desire, corrupts that good. Nevertheless the life brought to it remains. Such may be seen from a comparison with objects on which the sun's rays fall. There are some objects which accept them in a most beautiful way, converting them into the most beautiful colours, as a diamond, ruby, jacinth, sapphire, and other precious stones do. Other objects however do not accept them in that manner but convert them into the ugliest colours. The same point may be shown from the very characters of people. There are some who accept the good actions of another with every display of affection, while others convert them into evil. From this it becomes clear what the knowledge acquired from affections for good is which is meant by 'the land of Egypt as you come to Zoar' when the rational is 'like the garden of Jehovah'.
