Arcana Coelestia #5604
5604. 'Send the boy with me' means that he would be attached to him, that is to say, to the good of the Church represented by 'Judah'. This is clear from the meaning of 'sending with him' as being attached to him and not to the rest, for in what follows it is stated, 'I will be surety for him; from my hand you will require him'; and from the representation of Benjamin, to whom 'the boy' refers here, as interior truth, dealt with just above in 5600. The expression 'the boy' is used because in the Word that which is more internal, when compared with what is external, is called a boy or child, for the reason that more innocence is present in what is more internal than in what is more external, innocence being meant in the Word by 'a young child' and also by 'a boy (or child)', 5236.

5600. 'Have you a brother?' means regarding interior truth. This is clear from the representation of 'Benjamin' as the spiritual of the celestial, or what amounts to the same, the truth of good, which is interior truth. For 'Benjamin' is truth that has good within it, or the spiritual of the celestial, see 3969, 4592. This interior truth is what acts as the intermediary between truth from the Divine and truth within the natural.
