In an earlier thread, I walked through different interpretations of the man who wrestled with Jacob in Genesis 32. One idea is that Jacob is wrestling with an accusation against him: he has, in fact, taken his brother's blessing – Esau is rightfully angry.
The word translated as "wrestled" in Hebrew here is a word linked to "dust." It means "to get dusty."
And what is Adam, but a man made of the dust? That's how Adam is introduced. Interestingly, this word "wrestled" (אָבַק) is ONLY used in this section of the Bible; it's not a common biblical word.
I think we are being shown that Jacob is wrestling with this internal turmoil of how to deal rightly with his wicked brother, who he harmed, and who he believes wishes to harm him in return.
