1Moreover Yahweh’s word came to me, saying, 2“Son of man, set your face against Mount Seir, and prophesy against it, 3and tell it, ‘The Lord Yahweh says: “Behold, I am against you, Mount Seir, and I will stretch out my hand against you. I will make you a desolation and an astonishment. 4I will lay your cities waste, and you will be desolate. Then you will know that I am Yahweh.
5“‘“Because you have had a perpetual hostility, and have given over the children of Israel to the power of the sword in the time of their calamity, in the time of the iniquity of the end, 6therefore, as I live,” says the Lord Yahweh, “I will prepare you for blood, and blood will pursue you. Since you have not hated blood, therefore blood will pursue you. 7Thus I will make Mount Seir an astonishment and a desolation. I will cut off from it him who passes through and him who returns. 8I will fill its mountains with its slain. The slain with the sword will fall in your hills and in your valleys and in all your watercourses. 9I will make you a perpetual desolation, and your cities will not be inhabited. Then you will know that I am Yahweh.
10“‘“Because you have said, ‘These two nations and these two countries will be mine, and we will possess it,’ although Yahweh was there, 11therefore, as I live,” says the Lord Yahweh, “I will do according to your anger, and according to your envy which you have shown out of your hatred against them; and I will make myself known among them when I judge you. 12You will know that I, Yahweh, have heard all your insults which you have spoken against the mountains of Israel, saying, ‘They have been laid desolate. They have been given to us to devour.’ 13You have magnified yourselves against me with your mouth, and have multiplied your words against me. I have heard it.” 14The Lord Yahweh says: “When the whole earth rejoices, I will make you desolate. 15As you rejoiced over the inheritance of the house of Israel because it was desolate, so I will do to you. You will be desolate, Mount Seir, and all Edom, even all of it. Then they will know that I am Yahweh.’”
Jacob was the son of Isaac and Rebekah, born immediately after Esau, and Abraham was his grandfather. He achieved the right of the firstborn by trickery, in offering his older brother, Esau, food in exchange for the birthright, who cared little for this position. He also received the blessing of firstborn from his father Jacob before his death by cunning, and with the assistance of his mother Rebekah.
After his deception of Esau, receiving the blessing from his father, Jacob escaped to his uncle Laban, who in turn deceived Jacob into working for fourteen years for the marriage of Jacob to Leah, and then his beloved Rachel. Laban also sought to deceive Jacob of wages, but God intervened to ensure he would prosper. In a time of trial, when he feared the wrath of Esau, upon returning to the land of Canaan, Jacob had an encounter with God, and his name was changed to Israel, the one who wrestles with God. Even though his early life was characterized by deception, God worked through the situation to ensure that Jacob would be the one in the line of the patriarchs, to create a great nation and ultimately fulfill His purposes in the earth, especially through the future Messiah. The Messiah would guarantee the promise of the land to Abram and a person who would rule over Abraham's descendants, but also He would bring blessings to all the people of the earth (Gen 12:1-3).
In spite of Jacob's early failure by deception, God worked through him, and finally, Jacob became a different type of man after his struggle with God. As one has said,
"Despite Jacob’s faults, God chose him to be the leader of a great nation that still bears his name today. But for this, it is unlikely that we would know much about Jacob, who appears to be in the middle of events while the key players are those around him. There is no great wisdom or bravery in Jacob to speak of, and we are tempted to see him as little more than God’s passive instrument. If we are tempted to think that, because we aren’t in the spotlight performing great acts for God, we are unimportant to Him, then we should consider the life of Jacob and know that, in spite of our failings, God can and will still use us in His plan."
