Rabbi Samuel bar Nahmani taught that Jacob's adversary appeared to Jacob as an idol worshiper, and the Master has said in a Baraita that if an Israelite is joined by a heathen on the way, the Israelite should let the heathen walk on the right (so that the Israelite can keep the right hand nearest to the idol worshiper, so as to more easily defend against a sudden attack. Jacob must have done so, as his attacker injured the thigh that was nearest to him, the right thigh.) Rav Samuel bar Aha said in the name of Rava bar Ulla in the presence of Rav Papa that the attacker appeared to Jacob as one of the wise, and the Master (Rav Judah) said whoever walks at the right hand of his teacher is uncultured. (According to this view, Jacob regarded the other as a scholar and took his place at the other's left hand and so was injured in his right thigh, the side nearest to the other.) And the Rabbis said that he came from behind and dislocated both of Jacob's thighs. The Rabbis interpret , “As he wrestled with him,” like Rabbi Joshua ben Levi, who said teaches that the combatants threw up the dust of their feet to the Throne of Glory, for says, “As he wrestled (, "behe’avko") with him,” and says, “And, the clouds are the dust (, "avak") of his feet.”
