פּירוש אויף בראשית 32:25

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

ויאבק איש עמו, “a man began to wrestle with him.” The “man,” was an angel who had assumed the form of a human being. The angel, Esau’s protective power, had come to prevent Yaakov from escaping from Esau. He realised soon that G-d’s assurances to Yaakov were strong enough to protect him against being harmed by Esau. (Rash’bam)

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.
