1The vision of Obadiah. This is what the Lord Yahweh says about Edom. We have heard news from Yahweh, and an ambassador is sent among the nations, saying, “Arise, and let’s rise up against her in battle. 2Behold, I have made you small among the nations. You are greatly despised. 3The pride of your heart has deceived you, you who dwell in the clefts of the rock, whose habitation is high, who says in his heart, ‘Who will bring me down to the ground?’ 4Though you mount on high as the eagle, and though your nest is set among the stars, I will bring you down from there,” says Yahweh. 5“If thieves came to you, if robbers by night—oh, what disaster awaits you—wouldn’t they only steal until they had enough? If grape pickers came to you, wouldn’t they leave some gleaning grapes? 6How Esau will be ransacked! How his hidden treasures are sought out! 7All the men of your alliance have brought you on your way, even to the border. The men who were at peace with you have deceived you, and prevailed against you. Friends who eat your bread lay a snare under you. There is no understanding in him.”
8“Won’t I in that day”, says Yahweh, “destroy the wise men out of Edom, and understanding out of the mountain of Esau? 9Your mighty men, Teman, will be dismayed, to the end that everyone may be cut off from the mountain of Esau by slaughter. 10For the violence done to your brother Jacob, shame will cover you, and you will be cut off forever. 11In the day that you stood on the other side, in the day that strangers carried away his substance and foreigners entered into his gates and cast lots for Jerusalem, even you were like one of them. 12But don’t look down on your brother in the day of his disaster, and don’t rejoice over the children of Judah in the day of their destruction. Don’t speak proudly in the day of distress. 13Don’t enter into the gate of my people in the day of their calamity. Don’t look down on their affliction in the day of their calamity, neither seize their wealth on the day of their calamity. 14Don’t stand in the crossroads to cut off those of his who escape. Don’t deliver up those of his who remain in the day of distress. 15For the day of Yahweh is near all the nations! As you have done, it will be done to you. Your deeds will return upon your own head. 16For as you have drunk on my holy mountain, so all the nations will drink continually. Yes, they will drink, swallow down, and will be as though they had not been. 17But in Mount Zion, there will be those who escape, and it will be holy. The house of Jacob will possess their possessions. 18The house of Jacob will be a fire, the house of Joseph a flame, and the house of Esau for stubble. They will burn among them and devour them. There will not be any remaining to the house of Esau.” Indeed, Yahweh has spoken.
19Those of the South will possess the mountain of Esau, and those of the lowland, the Philistines. They will possess the field of Ephraim, and the field of Samaria. Benjamin will possess Gilead. 20The captives of this army of the children of Israel, who are among the Canaanites, will possess even to Zarephath; and the captives of Jerusalem, who are in Sepharad, will possess the cities of the Negev. 21Saviors will go up on Mount Zion to judge the mountains of Esau, and the kingdom will be Yahweh’s.
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."
