Jeremiah 30 – The days were to come when the fortunes of Israel will be restored. 2017

Jer 30:3
'For, behold, days are coming,' declares the LORD, 'when I will restore the fortunes of My people Israel and Judah.' The LORD says, 'I will also bring them back to the land that I gave to their forefathers, and they shall possess it.'"

The days were to come then the fortunes of Israel will be restored. This was first prophesied in Torah.

Deut. 30:3-5 then the LORD your God will restore you from captivity, and have compassion on you, and will gather you again from all the peoples where the LORD your God has scattered you. 4“If your outcasts are at the ends of the earth, from there the LORD your God will gather you, and from there He will bring you back. 5“And the LORD your God will bring you into the land which your fathers possessed, and you shall possess it; and He will prosper you and multiply you more than your fathers.

It is also prophesied in other places in the Tanakh.

Psalm 53:6 Oh, that the salvation of Israel would come out of Zion! When God restores His captive people, Let Jacob rejoice, let Israel be glad.

Ezek. 39:25-28 Therefore thus says the Lord GOD, “Now I shall restore the fortunes of Jacob, and have mercy on the whole house of Israel; and I shall be jealous for My holy name. 26“And they shall forget their disgrace and all their treachery which they perpetrated against Me, when they live securely on their own land with no one to make them afraid. 27“When I bring them back from the peoples and gather them from the lands of their enemies, then I shall be sanctified through them in the sight of the many nations. 28“Then they will know that I am the LORD their God because I made them go into exile among the nations, and then gathered them again to their own land; and I will leave none of them there any longer. 29“And I will not hide My face from them any longer, for I shall have poured out My Spirit on the house of Israel,” declares the Lord GOD.

Joel 3:1-2 “For behold, in those days and at that time, When I restore the fortunes of Judah and Jerusalem, 2I will gather all the nations, And bring them down to the valley of Jehoshaphat. Then I will enter into judgment with them there On behalf of My people and My inheritance, Israel, Whom they have scattered among the nations; And they have divided up My land.

Amos 9:14-15 “Also I will restore the captivity of My people Israel, And they will rebuild the ruined cities and live in them, They will also plant vineyards and drink their wine, And make gardens and eat their fruit. 15“I will also plant them on their land, And they will not again be rooted out from their land Which I have given them,” Says the LORD your God.

Obad 1:19-21 Then those of the Negev will possess the mountain of Esau, And those of the Shephelah the Philistine plain; Also, they will possess the territory of Ephraim and the territory of Samaria, And Benjamin will possess Gilead. 20And the exiles of this host of the sons of Israel, Who are among the Canaanites as far as Zarephath, And the exiles of Jerusalem who are in Sepharad Will possess the cities of the Negev. 21The deliverers will ascend Mount Zion To judge the mountain of Esau, And the kingdom will be the LORD’S.

Zeph. 3:20 “At that time I will bring you in, Even at the time when I gather you together; Indeed, I will give you renown and praise Among all the peoples of the earth, When I restore your fortunes before your eyes,” Says the LORD.
