Genesis 32:25

"And Jacob remained". He had forgotten [some] small vessels, and returned for them.

and a man wrestled: Heb. וַיֵאָבֵק. Menachem (p. 14) explains: And a man became covered with dust, derived from אָבָק, dust, for they were raising dust with their feet through their movements. I believe, however, that it is a term meaning that he attached himself, and it is an Aramaic expression [found in the Talmud] (Sanh. 63b):“After they became attached (דָּאִבִיקוּ) to it,”“and he would tie it (וְאָבִיק לֵיהּ מֵיבַק),” for so is the habit of two people who make strong efforts to throw each other down, that one embraces the other and attaches himself to him with his arms. Our Rabbis explained (Gen. Rabbah 77:3, 78:3) that this was the prince (guardian angel) of Esau.

And Jakob remained alone beyond the Jubeka; and an Angel contended with him in the likeness of a man. And he said, Hast thou not promised to give the tenth of all that is thine? And, behold, thou hast ten sons and one daughter: nevertheless thou hast not tithed them. Immediately he set apart the four firstborn of the four mothers, and there remained eight. And he began to number from Shimeon, and Levi came up for the tenth. Michael answered and said, Lord of the world, this is Thy lot. And on account of these things he (Michael) remained from God at the torrent till the column of the morning was ascending.

AND JACOB WAS LEFT ALONE. That is, for he had forgotten some small jars, and he returned for them. These are the words of Rashi. But in line with the plain meaning of Scripture, the verse, And he took them, and made them pass the brook, means that he made them [his family] pass together with him, and he made pass that which was his — [i.e., his camp and his belongings] — by commanding others to do it. He returned [to his camp after ferrying his family across], and he commanded that all others pass over the brook before him, and so he remained behind them.

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.

ויאבק, an angel engaged him in a physical fight, his purpose being to prevent Yaakov from fleeing. Only in this way could G’d’s promise to Yaakov that Esau would not harm him be fulfilled.

ויותר יעקב לבדו, he was the last one to leave from the camp as he was busy directing all his family and servants and chattels to cross the fording so that nothing would be left behind.

ויאבק איש עמו, this was the work of an angel at the instigation of G’d (that is why he is called איש). The description is parallel to Kings II 13,17 It is immaterial whether the instrument of the salvation is a merely symbolic one such as the arrows described in the Book of Kings which Elisha instructed King Yoash to shoot in the direction of the far away Kingdom of Aram. Salvation occurs at the end of a period of ups and downs, and though Yaakov/Israel suffered many reverses in his struggle with Esau, (in the historical global struggle between the two philosophies) in the end Yaakov triumphs. [freely translated as the author is ambiguous to my mind. Ed.] The blessing given by the angel here to Yaakov at the end of the struggle, at daybreak, symbolises the synopsis of Jewish history.

ויאבק איש עמו, he wrestled with him so intensely that a cloud of dust enveloped them while they were struggling.

איש, the same type of איש as in Joshua 5,13, i.e. an angel. This was the angel Gavriel, described as איש par excellence in Daniel 9,21. The reason why these angels are called איש is because they appear to the people with whom they converse in human guise. The types of angels who speak with man are referred to as איש, as they appear either in a vision or while the person to whom they appear is fully awake. G’d had sent this angel to Yaakov to strengthen his courage, not to fear Esau. If Yaakov could prevail over an angel, surely he had no reason to be afraid of an encounter with someone like Esau! The fact that the struggle lasted until daybreak was an allusion to Yaakov that after a period of night, i.e. problems, adversity, there would come a period of light, peace and prosperity coupled with security..

ויותר יעקב לבדו, “Yaakov remained behind all alone;” according to Rashi, Yaakov remained behind on the far bank of the Yabbok, to check if any insignificant item had been overlooked when they took all their belongings across. (Talmud, tractate Chulin, folio 91.) The letter ב in the word לבדו is supposed to be exchanged for the letter כ so that the word is to be read as לכדו. (small cans.) An alternate interpretation: it refers to בית הבד, a container in which small quantities of olive oil would be stored and which could be hidden easily.
