Arcana Coelestia # 5926
5926. 'And he fell on the neck of Benjamin' means an inmost joining to the intermediary. This is clear from the meaning of 'the neck' as an influx, communication, and joining together, dealt with in 3542, 3695, 3725 (strictly speaking it is a joining together of celestial things and spiritual ones, 5320, 5328, thus a joining of the internal celestial, which is 'Joseph', to the spiritual of the celestial, which is 'Benjamin'; consequently 'falling on the neck' means joining very closely to oneself, which is therefore an inmost joining together); and from the representation of 'Benjamin' as the intermediary, dealt with in 5411, 5413, 5443, 5679, 5686, 5688, 5689.

5443. 'And behold, the youngest is with our father today' means that they are also joined to spiritual good. This is clear from the representation of Benjamin, to whom 'the youngest' refers here, as the intermediary effecting a joining together, dealt with below; and from the representation of Jacob, who by now was Israel, to whom 'father' refers here, as spiritual good, dealt with in 3654, 4598. 'Benjamin' is the spiritual of the celestial, which is the intermediary, see 4592, 5411, 5413, 5419. That is to say, it is the intermediary that links the natural, or what is present in the natural, to the celestial of the spiritual, which is 'Joseph'. And since 'Benjamin' is the intermediary, while 'Israel' is spiritual good, the words 'behold, the youngest is with our father today' therefore mean a joining to spiritual good.
