5686. 'His brother, his mother's son' means the internal born from the natural as its mother. This is clear from the representation of Benjamin, to whom 'brother' and 'mother's son' refer here, as the internal, dealt with in 5469. And since this is the intermediary it comes into being from the celestial of the spiritual, represented by 'Joseph', as its father, and from the natural as its mother; for it must have its beginning in both these if it is to serve as an intermediary. So this is what is meant by the internal born from the natural as its mother. Also because the celestial of the spiritual, which is 'Joseph', had come into being in a similar way from the natural as its mother, but from the Divine as its father, 'Benjamin' is therefore called, as he was in actual fact by birth, 'his brother, his mother's son'; and in what immediately follows he is also addressed as 'son'. The name 'brother' is used by the Lord, who is meant here in the highest sense by 'Joseph', to refer to everyone who has any good of charity which he has received from the Lord. He is also referred to as 'his mother's son', but in this case 'mother' is used to mean the Church.

5469. 'Assuredly we are guilty concerning our brother' means that they were blameworthy because they had alienated the internal by their non-acceptance of good. This is clear from the meaning of 'being guilty' as being blameworthy and subject to the imputation [of sin] because good and truth have been cast aside, dealt with in 3400; and from the representation of Joseph, 'their brother' concerning whom they were guilty, as the internal which they had cast aside or alienated. For Joseph and Benjamin represent the internal aspect of the Church, while the remaining ten sons of Jacob represent its external aspect - 'Rachel', from whom Joseph and Benjamin were born, being the affection for interior truth, and 'Leah' the affection for exterior truth, 3758, 3782, 3793, 3819.

[2] In this chapter 'Joseph' represents the celestial of the spiritual or truth from the Divine, which is the internal; 'Benjamin' represents the spiritual of the celestial, which is the intermediary going forth from the internal; and the remaining 'ten sons of Jacob' represent the truths known to the external Church and so truths that are present in the natural, as stated many times above. This chapter also deals with the joining of the internal aspect of the Church to its external aspect, corporately and in every specific part; for each person individually must be a Church if he is to form part of the Church as a corporate whole. But in the highest sense the chapter deals with the way in which the Lord united the Internal to the External within His Human so as to make this Divine.
