Arcana Coelestia # 8079
8079. 'And if you do not redeem it you shall break its neck' means that if the truth of innocence is not present within it, it is to be separated and cast aside. This is clear from the meaning of 'not redeeming' as not ascribing it to the Lord but giving something else instead, as immediately above in 8078; and from the meaning of 'breaking the neck' as separating and casting aside. The reason why 'breaking the neck' has this meaning is that 'the neck' means a joining together of interior and exterior things, 3542, 3603, 3695, 3725, 5320, 5328, 5926, 6033, so that 'breaking the neck' is separating and casting aside, that is to say, doing so to merely natural faith if the truth of innocence is not present within it.
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.
