How to loose your sandal

If brothers are living together and one dies without a son his widow must not marry outside the family to a strange man. The brothers husband must take her as a wife and do his duty. The first born will carry the name of his brother so the name does not die out (Did you hear that all the Fountain family in New Zealand are the descendants of a man who died going out to India named Fountain to work with William Carey- so his name did not die out and he will have a large family in heaven-Ed) in Israel. But if he doesn't want to marry his brother's wife she goes to the town gate where the elders gather and tells them that he brother in law refuses to carry on in Israel the name and he will not do his duty. The elders of the town will call him and talk to him and if he insists in saying I won't marry her then she the widow will go to him in front of the elders and take off his sandal from his foot, spit in his face and say this is what happens to the man who will not build up his brother's family. He will be known in Israel as the man who lost his sandal.
