Hullin 91: Wrestling with the Angel

The discussion of the gid ha-nasheh leads into some lovely aggadic passages. First of all, did the sciatic nerve have to be in the right thigh to be prohibited at the Torah level or not? (Hint: It's a machloket). The Gemara breaks down the wrestling between Jacob and the angel from Genesis, to ensure that the injury would be in the right leg. But, again, not everyone thought that was necessary, and for that view, the sciatic nerve in each leg is equally prohibited. With further details about keeping a non-Jew, with whom one might be expected to spar, on the right side, and conversely, one must stay clear of the right side of the Torah scholar. Also, other midrashim/aggadot about Jacob -- how the stones became one larger stone to be his pillow, as it were (solving for a contradiction in the text). Plus, going back to that fight with the angel, and the ambiguities in that text. And the hint to exile and the leadership in both exile and the land of Israel.
