1The burden of Damascus.
“Behold, Damascus is taken away from being a city, and it will be a ruinous heap. 2The cities of Aroer are forsaken. They will be for flocks, which shall lie down, and no one shall make them afraid. 3The fortress shall cease from Ephraim, and the kingdom from Damascus, and the remnant of Syria. They will be as the glory of the children of Israel,” says Yahweh of Armies.
4“It will happen in that day that the glory of Jacob will be made thin, and the fatness of his flesh will become lean. 5It will be like when the harvester gathers the wheat, and his arm reaps the grain. Yes, it will be like when one gleans grain in the valley of Rephaim. 6Yet gleanings will be left there, like the shaking of an olive tree, two or three olives in the top of the uppermost bough, four or five in the outermost branches of a fruitful tree,” says Yahweh, the God of Israel. 7In that day, people will look to their Maker, and their eyes will have respect for the Holy One of Israel. 8They will not look to the altars, the work of their hands; neither shall they respect that which their fingers have made, either the Asherah poles or the incense altars. 9In that day, their strong cities will be like the forsaken places in the woods and on the mountain top, which were forsaken from before the children of Israel; and it will be a desolation. 10For you have forgotten the God of your salvation, and have not remembered the rock of your strength. Therefore you plant pleasant plants, and set out foreign seedlings. 11In the day of your planting, you hedge it in. In the morning, you make your seed blossom, but the harvest flees away in the day of grief and of desperate sorrow.
12Ah, the uproar of many peoples who roar like the roaring of the seas; and the rushing of nations that rush like the rushing of mighty waters! 13The nations will rush like the rushing of many waters, but he will rebuke them, and they will flee far off, and will be chased like the chaff of the mountains before the wind, and like the whirling dust before the storm. 14At evening, behold, terror! Before the morning, they are no more. This is the portion of those who plunder us, and the lot of those who rob us.
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."
