1Moreover Yahweh’s word came to Jeremiah the second time, while he was still locked up in the court of the guard, saying, 2“Yahweh who does it, Yahweh who forms it to establish it—Yahweh is his name, says: 3‘Call to me, and I will answer you, and will show you great and difficult things, which you don’t know.’ 4For Yahweh, the God of Israel, says concerning the houses of this city and concerning the houses of the kings of Judah, which are broken down to make a defense against the mounds and against the sword: 5‘While men come to fight with the Chaldeans, and to fill them with the dead bodies of men, whom I have killed in my anger and in my wrath, and for all whose wickedness I have hidden my face from this city, 6behold, I will bring it health and healing, and I will cure them; and I will reveal to them abundance of peace and truth. 7I will restore the fortunes of Judah and Israel, and will build them as at the first. 8I will cleanse them from all their iniquity by which they have sinned against me. I will pardon all their iniquities by which they have sinned against me and by which they have transgressed against me. 9This city will be to me for a name of joy, for praise, and for glory, before all the nations of the earth, which will hear all the good that I do to them, and will fear and tremble for all the good and for all the peace that I provide to it.’”
10Yahweh says: “Yet again there will be heard in this place, about which you say, ‘It is waste, without man and without animal, even in the cities of Judah, and in the streets of Jerusalem, that are desolate, without man and without inhabitant and without animal,’ 11the voice of joy and the voice of gladness, the voice of the bridegroom and the voice of the bride, the voice of those who say, ‘Give thanks to Yahweh of Armies, for Yahweh is good, for his loving kindness endures forever;’ who bring thanksgiving into Yahweh’s house. For I will cause the captivity of the land to be reversed as at the first,” says Yahweh.
12Yahweh of Armies says: “Yet again there will be in this place, which is waste, without man and without animal, and in all its cities, a habitation of shepherds causing their flocks to lie down. 13In the cities of the hill country, in the cities of the lowland, in the cities of the South, in the land of Benjamin, in the places around Jerusalem, and in the cities of Judah, the flocks will again pass under the hands of him who counts them,” says Yahweh.
14“Behold, the days come,” says Yahweh, “that I will perform that good word which I have spoken concerning the house of Israel and concerning the house of Judah.
15“In those days and at that time,
I will cause a Branch of righteousness to grow up to David.
He will execute justice and righteousness in the land.
16In those days Judah will be saved,
and Jerusalem will dwell safely.
This is the name by which she will be called:
Yahweh our righteousness.”
17For Yahweh says: “David will never lack a man to sit on the throne of the house of Israel. 18The Levitical priests won’t lack a man before me to offer burnt offerings, to burn meal offerings, and to do sacrifice continually.”
19Yahweh’s word came to Jeremiah, saying, 20“Yahweh says: ‘If you can break my covenant of the day and my covenant of the night, so that there will not be day and night in their time, 21then my covenant could also be broken with David my servant, that he won’t have a son to reign on his throne; and with the Levitical priests, my ministers. 22As the army of the sky can’t be counted, and the sand of the sea can’t be measured, so I will multiply the offspring of David my servant and the Levites who minister to me.’”
23Yahweh’s word came to Jeremiah, saying, 24“Don’t consider what this people has spoken, saying, ‘Has Yahweh cast off the two families which he chose?’ Thus they despise my people, that they should be no more a nation before them.” 25Yahweh says: “If my covenant of day and night fails, if I have not appointed the ordinances of heaven and earth, 26then I will also cast away the offspring of Jacob, and of David my servant, so that I will not take of his offspring to be rulers over the offspring of Abraham, Isaac, and Jacob; for I will cause their captivity to be reversed and will have mercy on them.”
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."
