25:7-10
The situation of the brother refusing to fulfil the duties outlined in the previous section is now outlined. At first pressure is brought to bear on the brother by the elders, stressing his obligations to his deceased brother. If this failed to have any effect, then the widow was to spit in his face and denounce him. So the man would be dishonoured.
25:11,12
The Bible is wonderfully down to earth, dealing with all sorts of practicalities. So if two men are fighting, and the wife of one of them seeks to help her husband by grabbing the testicles of the other man, then she was to be severely punished. The punishment seems rather harsh, if you do a google search there are various possible explanations, none of them wholly satisfying. It could be an over-literal translation. Anyway, I don’t know of anyone who bases there theology on these two verses, so we will move on.
