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.

389. 'Everyone finding him would kill him' means that all evil and falsity would destroy him. This follows from what is said above. The position in fact is this: When a person divests himself of charity, he in that case separates himself from the Lord. It is charity alone, or love towards the neighbour and compassion, which joins man to the Lord. Without charity the two are disjoined, and when they are disjoined man is left to himself, that is, to the proprium. In that case whatever he thinks is false, and whatever he wills is evil. These are the things that kill man, that is, lead to his having no life at all.
