What angel wrestled Jacob?

Although modern English translations often use the Word 'angel', Jacob did not wrestle with an angel, but with a god - el. So the question could be about what god wrestled with Jacob.

In an ancient tradition inserted into the life story of Jacob at Genesis 32:24ff, he was left alone and wrestled with a man all night until the break of day. Even though his leg was dislocated, Jacob refused to let his opponent go unless he blessed Jacob. That the 'man' was a god is amply demonstrated - Jacob asked for his blessing, and he had the prerogative of changing Jacob's name. The new name he gave Jacob was Israel (generally assumed to mean "wrestled with God'). If the man who wrestled with Jacob was a god, then Jacob was also a god in the very early tradition behind this account, as demonstrated by the fact that he was such an even match for his opponent. And if the opponent was a god, he was also a sun god - daybreak signalled the end of the contest, he had to leave Jacob before the sun could rise, then the sun rose upon Jacob. There is evidence elsewhere in The Bible that suggests Jacob was worshipped as the moon god in very early times before his story evolved into that of a mortal hero. Jacob called the place Peniel ('the face of God') because he had seen God face to face.

When we accept that this was once the story of a contest between two gods, or even if we imagine that the patriarch Jacob could wrestle a god for the entire night, then we have few choices but to see that the god who wrestled Jacob was, in pre-biblical times, the sun god.
