5593. 'Unless your brother is with you' means unless the intermediary is with you. This is clear from what has been stated above in 5586, 5587, about Benjamin, to whom 'brother' refers here, being the intermediary.

5586. 'Unless your brother is with you' means unless the intermediary is with you. This is clear from the representation of 'Benjamin' as the intermediary, dealt with in 5411, 5413, 5443. The intermediary represented by 'Benjamin' serves as the link between the internal and the external, that is, between the spiritual man and the natural man; also, it is the truth of good that goes forth from truth from the Divine, represented by 'Joseph'. This truth of good is called the spiritual of the celestial - 'Benjamin' being the spiritual of the celestial, see 3969, 4592. A person's internal and external are completely distinct and separate from each other; for his internal dwells in the light of heaven, his external in the light of the world. And being completely distinct and separate they cannot be joined together except through the intermediary which derives its existence from both of them.
