פירוש על הושע 12:5

he wept i.e., the angel wept. [from Chullin 92a]

and beseeched him When he said to him, “I will not let you go unless you bless me” (Gen. 32:26), and the angel was begging him, “Let me go now. Eventually, the Holy One, blessed be He, will reveal Himself to you in Bethel, and there you will find Him, and there He will speak with us, and He and I will agree with you concerning the blessings that Isaac blessed you.” Now that angel was Esau’s genius, and he was contesting the blessings.
