4803. A matter wholly unknown in the world and worthy of mention is this: The states in which good spirits and angels live undergo constant change and perfection. In this way they are conveyed to the more internal parts of the province in which they dwell, and so into more excellent functions. For in heaven purification takes place constantly, which is so to speak a new creation. Yet the situation is that no angel to all eternity can possibly attain complete perfection. The Lord alone is the perfect One, He being the root and the source of all perfection. Those who correspond to the mouth constantly wish to be speaking, for speaking gives them utmost pleasure. While undergoing perfection they are restricted to speaking nothing but that which is beneficial to companions, the community, heaven, and the Lord. The delight they take in speaking in that way grows in the measure that the desire to regard themselves in what they speak and to strive after wisdom from what is properly their own passes away from them.

9516. 'And their faces of a man towards his brother' means truth and good joined together. This is clear from the meaning of 'the face' as the interiors, at this point looking towards and being joined to, for when two are looking each towards the other they join themselves together on the level of interiors (interiors being meant by 'the face', 1999, 2434, 3527, 3573, 4066, 4796-4805, 5102, 5165, 5168, 5695, 9306); and from the meaning of 'man towards brother' as mutually, dealt with in 4725, so that truth joined to good is meant. For 'man' means truth, 3134, 3309, 3459, 4725, 7716, 9007, and 'brother' good, 367, 2360, 3303, 3803, 3815, 4121, 4191, 5409, 5686, 5692, 6756.

5409. 'Joseph's ten brothers' means such truths known to the Church as were in agreement with one another. This is clear from the meaning of 'brothers' as truths known to the Church. These truths are called 'Joseph's brothers' ('Joseph' representing truth received from the Divine) by virtue of their agreement with one another; for that agreement causes them to exist joined together like one brother to another. 'The sons of Jacob' means all the truths of faith or the truths as a general whole that are known by the Church, 5403; and the expression 'Joseph's brothers' has a similar meaning, though this is because of their agreement with one another. Jacob's ten sons by Leah mean the truths known to the external Church, but Jacob's two sons by Rachel mean the truths known to the internal Church, as is evident from what has been shown regarding Leah and Rachel. That is to say, it has been shown that 'Leah' is the affection for exterior truth and 'Rachel' the affection for interior truth, both dealt with in 3758, 3782, 3793, 3819. Also, the internal Church and the external Church are 'brothers', see 1221. The Lord Himself therefore uses the word 'brothers' to describe truths and resulting forms of good which exist in agreement with one another by virtue of charity and faith, that is, to describe people who know truths and from these desire what is good: In Matthew,

The king will say to them, Truly I say to you, Insofar as you did it to one of the least of these My brothers you did it to Me. Matthew 25:40.

And elsewhere,

Jesus answered them, saying, Who is My mother, or My brothers? And looking round about He said, Behold My mother and My brothers! For whoever does the will of God is My brother, and My sister, and My mother. Mark 3:33-35; Matthew 12:49; Luke 8:21.
