Like in Rumpelstiltskin, the young naive fair maiden had promised her first born in a deal made without the knowledge of the father or husband. The tale is telling us of the manipulating techniques of the jew and to what extent they can get into another man’s business.
The father, through desperation, ie Jewish loans with crippling interest, had charged his daughter to the king that she may spin him gold from straw.
In the modern sense the allegory I wish to use is that of an imp who ties you down in your sleep and proceeds to smash your nose in. Not only are you in pain and shock, reason is sought, and what better reason than to have no reason so as to confuse and frustrate. Like the poor girl trying to guess the name of the villainous rogue trying to have away with the small baby. Just let that sink in a second. “Ours is not to reason why, ours is but to do and die.” Alfred Lord Tennyson
