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.
Judges 6:12-14
12
The angel of Yahweh appeared to him, and said to him, "Yahweh is with you, you mighty man of valor!"
13
Gideon said to him, "Oh, my lord, if Yahweh is with us, why then has all this happened to us? Where are all his wondrous works which our fathers told us of, saying, 'Didn't Yahweh bring us up from Egypt?' But now Yahweh has cast us off, and delivered us into the hand of Midian."
14
Yahweh looked at him, and said, "Go in this your might, and save Israel from the hand of Midian. Haven't I sent you?"
