5736. 'And you are to put my cup, the cup made of silver, in the mouth of the pouch of the youngest' means interior truth granted to the intermediary. This is clear from the meaning of 'the cup made of silver' as the truth of faith which flows from the good of charity, dealt with in 5120 - which 'cup', since it is said to be 'mine', that is, Joseph's, means interior truth (since 'Benjamin' represents the intermediary - including its truth - he represents interior truth, 5600, 5631, thus spiritual truth, 5639); from the meaning of 'the mouth of the pouch', when used in reference to Benjamin, the intermediary, as the place where it is joined on to the natural (for to be an intermediary the intermediary must communicate with the external and with the internal, 5411, 5413, 5586, the exterior of it being the natural here); and from the representation of Benjamin, to whom 'the youngest' refers here, as the intermediary, dealt with in 5411, 5413, 5443, 5688. All this shows what is meant by Joseph's putting his cup made of silver in Benjamin's pouch.

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.
