In chapters 30-33, the LORD shines a bright ray of hope into the midst of the dark days of Babylon's final siege of Jerusalem. Jeremiah is in prison. Nebuchadnezzar's armies surround Jerusalem and are making steady progress toward their inevitable conquest of the city.
Now that the promised judgment is certain, and all human hope of escape has vanished, the LORD says that just as surely as His promises of judgment have been fulfilled, so, His promises to restore are certain (32:42).
Here is a brief overview of these four chapters:
Future Restoration is Promised: Preceded by the Time of Jacob's Trouble. (ch.30)
...make a New Covenant... write my laws in their hearts.
...establish them in their land... and in their city.
The future Restoration is Certain,
as illustrated by Jeremiah's Purchase of Hanameel's Real Estate. (ch.32)
The future Restoration is Secured: in the Person of David's Righteous Branch. (ch.33)
The Security of the Kingdom of David, ch. 33
"The chapter contains three sections, each section being, in its turn, constructed in triplets." [GWms] The major points (Roman numerals and Letters) of the outline below are from George Williams (GWms).
As Jeremiah struggles to imagine a future day of restoration, due to the pressing realities of the present destruction (cp. Jer 32:24,25), he is counseled to place complete confidence in the LORD.
The LORD identifies Himself (v.2) as the "maker" {ie., doer, accomplisher} of His purposes.
(cp. this word in v.9 "I do... I procure," and v.15 "execute")
It is He, the LORD, the ever-living One, who has "formed" and "established"
The promises of restoration, in the preceding verses, were only partially fulfilled by the return of the captives in the days of Ezra and Nehemiah. Although that restoration would prove to be temporary, it marked the beginning of "that good thing which I have promised," ie., the ultimate and permanent restoration (cp. 32:37-42).
in those days, and at that time (v.15a) - ie., during the period of partial restoration (which ended in 70 AD),
"I will cause the Branch of Righteousness to grow up {to sprout, to spring up} unto David" (cp. Isa 11:1).
The presence of Jewish people (including some of David's lineage) in the land, and the presence of shepherds in the fields of Judah, were aspects of that partial restoration (v.12-15a) and essential points in the account of His first coming (eg., Luk 2:1-11).
in those days (v.15b,16) - ie., in the days of His future reign (as described in v.15b),
Judah shall be saved, and Jerusalem shall dwell safely. cp. Jer 30:10,11
This name is applied to the Messiah, the Savior and King, in Jer 23:5,6. But here, it is this name whereby "she (ie., Jerusalem) shall be called." That is, His name will be applied to her, as the bridegroom's name is given to his bride.
Today, while no king sits upon the throne of the nation of Israel (Hos 3:4), David does not lack a man for that throne. Until the time appointed for His earthly reign, He waits upon another Throne (Psa 110:1; Rev 3:21; Eph 1:20-23; Php 2:9-11).
Today, while Israel has no priest to offer sacrifices in an earthly Temple (Hos 3:4), they do not lack a Priest in the presence of God (Heb 4:14-16). Their great High Priest offered Himself as the one all sufficient sacrifice for the sin of His people (Heb 10:11-18). In the restoration, Israel will be a nation of priests, whose sacrifices will remember the price of redemption which our High Priest paid in full (Isa 56:7; 61:6). That restoration is foreshadowed in the spiritual nation of believer-priests, today (1Pet 2:5,9).
In this closing section of ch. 33, the tokens of the LORD's power and faithfulness to fulfill His unconditional covenant with the seed and nation of Israel (Jer 31:35-37) are applied to His unconditional covenant with David (cp. v.14-17; 2Sam 23:1-5; Psa 89:3-4,29,36; 132:11,17; Luk 1:31-33).
Here, the tokens given to Abraham concerning the multiplying of his seed (Gen 13:16; 15:5) are applied also to the multiplying of the seed of David (ie., of the Messiah, cp. Isa 53:10,11; Psa 22:30; Rev 7:9,10), and of the multiplying of priests (as in v.18 above).
Jeremiah's contemporaries thought that the LORD had cast off His people (v.24). As they saw it, He had forsaken, not just one, but both families (the northern and the southern kingdoms of Israel). But their view revealed their unbelief: "Thus they have despised my people that they should no longer be a people before Me."
Most of Christendom has fallen into this same error. Contrary to their unbelief, the LORD makes it unmistakeably clear that He will never forsake the seed of Jacob (the children of Israel) nor the seed of David (the King of His anointing, cp. Psalm 2), but will fulfill His promises of complete restoration.
In the last line of v.26, "I will" is doubled (in the HB text), emphasizing that the LORD alone will perform these things: "...for I will cause their captivity to return, and I will have mercy {ie., compassion, as translated in Deu 30:3} upon them."
