Arcana Coelestia #4315
4315. In the internal historical sense 'therefore the children of Israel do not eat the sinew of that which was displaced, which is on the hollow of the thigh' means that those descendants ought to know this.

Genesis 34:27-29
27
Jacob's sons came on the dead, and plundered the city, because they had defiled their sister.
28
They took their flocks, their herds, their donkeys, that which was in the city, that which was in the field,
29
and all their wealth. They took captive all their little ones and their wives, and took as plunder everything that was in the house.
