As we've mentioned on several occasions throughout our S.A.L.T. series, Chazal identify the mysterious man/being who attacked Yaakov in the middle of the night as "Saro shel Esav," Esav's heavenly angel. One source, however, appears at first glance to indicate otherwise. Pirkei D'Rabbi Eliezer 36 writes that when the angel changed Yaakov's name to Yisrael (32:29), he responded to Yaakov's request that the angel reveal his name (despite the fact that the Torah records this request as occurring only after the name change).
