(25) Jacob was left alone. And a figure wrestled with him until the break of dawn. (26) When he saw that he had not prevailed against him, he wrenched Jacob’s hip at its socket, so that the socket of his hip was strained as he wrestled with him. (27) Then he said, “Let me go, for dawn is breaking.” But he answered, “I will not let you go, unless you bless me.” (28) Said the other, “What is your name?” He replied, “Jacob.” (29) Said he, “Your name shall no longer be Jacob, but Israel, for you have striven with beings divine and human, and have prevailed.” (30) Jacob asked, “Pray tell me your name.” But he said, “You must not ask my name!” And he took leave of him there.

(29) I have it in my power to do you harm; but the God of your father said to me last night, ‘Beware of attempting anything with Jacob, good or bad.’

(24) After taking them across the stream, he sent across all his possessions. (25) Jacob was left alone. And a figure wrestled with him until the break of dawn.

ויותר יעקב AND JACOB WAS LEFT ALONE — He had forgotten some small jars and he returned for them (Chullin 91a).

ויותר יעקב לבדו, after he had transferred all his belongings to the other side of the river, so that the only one still to be brought across was he himself. The reason that he wanted to cross only after everyone else had already crossed was that he intended to flee in a different direction so as to avoid a face to face encounter with Esau.

AND HE SAW THAT HE PREVAILED NOT AGAINST HIM. Ye angels of His, ye mighty in strength, that fulfill His word. Because of this the angel could not prevail against him to harm him for it was not permitted to him to do other than that which he did to him, namely, to disjoint the hollow of his thigh. Now the Rabbis have said in Bereshith Rabbah: “He touched all the righteous people who were destined to come from Jacob. This refers to the generation of religious persecution.” The purport of this Midrash is that this entire event constitutes a hint to his generations, indicating that there will be a generation from the seed of Jacob against whom Esau [Rome] will prevail to the extent of almost uprooting his seed. This occurred in one generation during the period of the Sages of the Mishnah, which was the generation of Rabbi Yehudah ben Baba and his companions. As they said: “Rabbi Chiya bar Abba said, ‘If a person were to tell me, “Give your life for the sanctification of the Name of the Holy One, blessed be He,” I would give it, providing only that they slay me immediately. But in the generation of religious persecution I could not endure!’ And what did the Romans do in that generation? They would bring iron balls and heat them in fire and then place them under their arm-pits and cause their death.” And there are other generations in which they have done to us such things as these and even worse, but we have endured and it has passed over us, just as it is hinted in the verse, And Jacob came in peace.

MISHNA: The prohibition of eating the sciatic nerve applies both in Eretz Yisrael and outside of Eretz Yisrael, in the presence of, i.e., the time of, the Temple and not in the presence of the Temple, and with regard to non-sacred animals and with regard to sacrificial animals. And it applies to domesticated animals and to undomesticated animals, to the thigh of the right leg and to the thigh of the left leg. But it does not apply to a bird, due to the fact that the verse makes reference to the sciatic nerve as being “upon the spoon of the thigh” (Genesis 32:33), and a bird has no spoon of the thigh.
