"These were the kings who reigned in Edom before any Israelite king reigned..." 43a

This passage indicates that the two (Edom and Israel) did not get along with each other. In a small pocket of land called the Promised Land, the two are still fighting for the hegemony. Edomites stem from Esau, Israel from Jacob. Esau and Jacob are twin brothers. While in the womb of their mother Rebekah they did not get along well. Their wrestling match in the mother's womb grew (often times) wild that Rebekah had to cry out to the Lord, and the Lord answered, "Two nations are in your womb...one will be stronger than the  other, and the older will serve the younger." Genesis 25:23

Is it (the older will serve the  younger) the answer? Yes it is! When Jacob rules Edom (thus when Edom serves Jacob) the pain (as in the mother's womb) will die down. The two can shake hands, and there will be peace.  Isn't it because of this truth that the Lord said, "Esau I hate, Jacob I love?" Malachi 3:1

This is consistent with what King Solomon says, "For 3 things the earth is disquieted, for 4 it cannot bear." Proverbs 30:21-23 And the first on the list comes a servant becoming a ruler. [Disquieted = "raqaz in Hebrew; tremble, quake, be excited, be perturbed, enraged, troubled, shake...] 

The question then becomes, "What is evil of Esau that he be subjugated, filling a servant's position? What is good of Jacob that he ought to rule?" The answer used to be "Oh, Esau exemplifies a man living after flesh, Jacob/Israel a man living according to the Spirit." Further Jesus said, "Flesh counts for nothing; spirit gives life to man." John 6:63

Still the question remains: Is flesh all evil? The answer is no. Why not? The Apostle Paul says, "Everything God created is good, nothing is to be rejected if it is received with thanksgiving." 1Ti 4:4

The message then is not to demonize flesh but keep it in the right place, knowing that doing otherwise will come with the consequence, the "going down" effect, just as is said of why a seesaw is made:

The reason why a seesaw was made for two people is that when you go down, there would always be someone there to lift you up again.
