Gen 32&33 - Esau's kiss - Greeting? Or bite on the neck? Jacob gets a new name and a dislocated hip

Gen 32:24
Then Jacob was left alone, and a man wrestled with him until daybreak.

Gen 32:25
And when he saw that he had not prevailed against him, he ouched the socket of his thigh; so the socket of Jacob's thigh was dislocated while he wrestled with him.

Jacob wrestled with a "man" as mentioned here. In Hosea 12:4, we are told it was an "angel." In Hosea 12:5 it would appear that this "angel" was a manifestation of Elohim Himself. A Jewish commentary published by the Jewish Publication Society says the identification of the opponent of Jacob is unknown. They went as far as to say that it could have been the spiritual entity of Esau himself. I find that humorous. This event certainly seems to describe Elohim appearing as a man. He is named "Elohim" twice in this passage. The fact that He merely touched Jacob's hip and disabled him is ample evidence to show that He could have defeated Jacob at anytime. We are not told if the ensuing pain resulting in a limp was temporary or for the rest of his life. So what was the purpose in wrestling with Jacob? Apparently Elohim was demonstrating to Jacob the futility of attempting to handle this situation with Esau on His own. If Jacob tries to handle this situation himself, He is struggling against Elohim. While it is good to prepare, he needs to place this situation in the hands of Elohim and trust that His will will be done.

Gen 32:27
So he said to him, "What is your name?" And he said, "Jacob."

Gen 32:28
And he said, "Your name shall no longer be Jacob, but Israel; for you have striven with God and with men and have prevailed."

Elohim wanted to leave before the sun rises. Apparently He did not want Jacob to see His face. Jacobs response shows that Jacob now realizes that he cannot overcome with his own power. He requires the blessing of Elohim in order to succeed. That appears the be the purpose of this episode. The name change has been the subject of much controversy. The Jewish Publication Society says the full meaning of "Israel" is not fully know. The context of this passage would appear to mean "one who struggles with El." The name Jacob means "the supplanter." With this name change comes a character change also. Now he learns to rely on Elohim in times of distress.

Gen 33:4
Then Esau ran to meet him and embraced him, and fell on his neck and kissed him, and they wept.

The way the text is translated, it would appear that Esau is genuinely moved. The text is translated to say that He embraced him and kissed him. However, the Hebrew word used for "he kissed him" is written very strangely in the Masoretic text. It is shows up with apparently 14 vowel points and its precise meaning is not known. It has been thought by ancient sages to mean that Esau was at least disingenuous with his kiss. Some ancient sages have said it means that Esau wanted to "bite him on the neck until he was dead." With that being the case, the tears would have been tears of relief for Jacob and tears of frustration for Esau who was not able to kill the man that he hated so much. Even recently, when the nation of Israel would sign a peace agreement with a man as evil as Yassir Arafat, the Jewish people would refer to the handshake with Arafat as "Esau's Kiss."
