1In that day, Yahweh with his hard and great and strong sword will punish leviathan, the fleeing serpent, and leviathan, the twisted serpent; and he will kill the dragon that is in the sea.
2In that day, sing to her, “A pleasant vineyard! 3I, Yahweh, am its keeper. I will water it every moment. Lest anyone damage it, I will keep it night and day. 4Wrath is not in me, but if I should find briers and thorns, I would do battle! I would march on them and I would burn them together. 5Or else let him take hold of my strength, that he may make peace with me. Let him make peace with me.”
6In days to come, Jacob will take root. Israel will blossom and bud. They will fill the surface of the world with fruit. 7Has he struck them as he struck those who struck them? Or are they killed like those who killed them were killed? 8In measure, when you send them away, you contend with them. He has removed them with his rough blast in the day of the east wind. 9Therefore by this the iniquity of Jacob will be forgiven, and this is all the fruit of taking away his sin: that he makes all the stones of the altar as chalk stones that are beaten in pieces, so that the Asherah poles and the incense altars shall rise no more. 10For the fortified city is solitary, a habitation deserted and forsaken, like the wilderness. The calf will feed there, and there he will lie down, and consume its branches. 11When its boughs are withered, they will be broken off. The women will come and set them on fire, for they are a people of no understanding. Therefore he who made them will not have compassion on them, and he who formed them will show them no favor.
12It will happen in that day that Yahweh will thresh from the flowing stream of the Euphrates to the brook of Egypt; and you will be gathered one by one, children of Israel.
13It will happen in that day that a great trumpet will be blown; and those who were ready to perish in the land of Assyria, and those who were outcasts in the land of Egypt, shall come; and they will worship Yahweh in the holy mountain at Jerusalem.
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."
