창세기 32:26의 Halakhah

It is from the roots of this commandment [that it is to serve as] a hint to Israel that though they will suffer many troubles in the exile by the hand of the nations and by the hand of the [descendants] of Esav (i.e. the Christians), [the Jews] should trust that they will not perish, but rather that their descendants and name will stand firm forever, and that their redeemer will come and redeem them from their oppressor. And in continually remembering this idea through the commandment that serves as a reminder, they will stand firm in their faith and righteousness forever. And this hint [stems from the fact that] that the angel who fought with Yaakov our forefather - who according to tradition (Bereshit Rabbah 78) was the guardian angel of Esav - wished to eliminate Yaakov from the world, he and his descendants; but he could not [get the better] of him, (Genesis 32:26) but anguished him in injuring his thigh. Likewise, Esav's seed anguishes the seed of Yaakov; but in the end, [the latter] will be saved from them. As we find (Genesis 32:32) with respect to [our] forefather that the sun shone to heal him and he was saved from pain, so will the sun of the messiah shine and he will heal us from our pain and redeem us speedily in our days, amen!
