Here, I. Jeremiah is directed to write what God had spoken to him, which perhaps refers to all the foregoing prophecies. He must write them and publish them, in hopes that those who had not profited by what he said upon once hearing it might take more notice of it when in reading it they had leisure for a more considerate review. Or, rather, it refers to the promises of their enlargement, which had been often mixed with his other discourses. He must collect them and put them together, and God will now add unto them many like words. He must write them for the generations to come, who should see them accomplished, and thereby have their faith in the prophecy confirmed. He must write them not in a letter, as that in the chapter before to the captives, but in a book, to be carefully preserved in the archives, or among the public rolls or registers of the state. Daniel understood by these books when the captivity was about coming to an end, Dan 9:2. He must write them in a book, not in loose papers: "For the days come, and are yet at a great distance, when I will bring again the captivity of Israel and Judah, great numbers of the ten tribes, with those of the two," Jer 30:3. And this prophecy must be written, that it may be read then also, that so it may appear how exactly the accomplishment answers the prediction, which is one end of the writing of prophecies. It is intimated that they shall be beloved for their fathers' sake (Rom 11:28); for therefore God will bring them again to Canaan, because it was the land that he gave to their fathers, which therefore they shall possess.

II.He is directed what to write. The very words are such as the Holy Ghost teaches, Jer 30:4. These are the words which God ordered to be written; and those promises which are written by his order are as truly his word as the ten commandments which were written with his finger. 1. He must write a description of the fright and consternation which the people were now in, and were likely to be still in upon every attack that the Chaldeans made upon them, which will much magnify both the wonder and the welcomeness of their deliverance (Jer 30:5): We have heard a voice of trembling - the shrieks of terror echoing to the alarms of danger. The false prophets told them that they should have peace, but there is fear and not peace, so the margin reads it. No marvel that when without are fightings within are fears. The men, even the men of war, shall be quite overwhelmed with the calamities of their nation, shall sink under them, and yield to them, and shall look like women in labour, whose pains come upon them in great extremity and they know that they cannot escape them, Jer 30:6. You never heard of a man travailing with child, and yet here you find not here and there a timorous man, but every man with his hands on his loins, in the utmost anguish and agony, as women in travail, when they see their cities burnt and their countries laid waste. But this pain is compared to that of a woman in travail, not to that of a death-bed, because it shall end in joy at last, and the pain, like that of a travailing woman, shall be forgotten. All faces shall be turned into paleness. The word signifies not only such paleness as arises from a sudden fright, but that which is the effect of a bad habit of body, the jaundice, or the green sickness. The prophet laments the calamity upon the foresight of it (Jer 30:7): Alas! for that day is great, a day of judgment, which is called the great day, the great and terrible day of the Lord (Joe 2:31, Jde 1:6), great, so that there has been none like it. The last destruction of Jerusalem is thus spoken of by our Saviour as unparalleled, Mat 24:21. It is even the time of Jacob's trouble, a sad time, when God's professing people shall be in distress above other people. The whole time of the captivity was a time of Jacob's trouble; and such times ought to be greatly lamented by all that are concerned for the welfare of Jacob and the honour of the God of Jacob. 2. He must write the assurances which God had given that a happy end should at length be put to these calamities. (1.) Jacob's troubles shall cease: He shall be saved out of them. Though the afflictions of the church may last long, they shall not last always. Salvation belongs to the Lord, and shall be wrought for his church. (2.) Jacob's troublers shall be disabled from doing him any further mischief, and shall be reckoned with for the mischief they have done him, Jer 30:8. The Lord of hosts, who has all power in his hand, undertakes to do it: "I will break his yoke from off thy neck, which has long lain so heavy, and has so sorely galled thee. I will burst thy bonds and restore thee to liberty and ease, and thou shalt no more be at the beck and command of strangers, shalt no more serve them, nor shall they any more serve themselves of thee; they shall no more enrich themselves either by thy possessions or by thy labours." And, (3.) That which crowns and completes the mercy is that they shall be restored to the free exercise of their religion again, Jer 30:9. They shall be delivered from serving their enemies, not that they may live at large and do what they please, but that they may serve the Lord their God and David their king, that they may come again into order, under the established government both in church and state. Therefore they were brought into trouble and made to serve their enemies because they had not served the Lord their God as they ought to have done, with joyfulness and gladness of heart, Deu 28:47. But, when the time shall come that they should be saved out of their trouble, God will prepare and qualify them for it by giving them a heart to serve him, and will make it doubly comfortable by giving them opportunity to serve him. Therefore we are delivered out of the hands of our enemies, that we may serve God, Luk 1:74, Luk 1:75. And then deliverances out of temporal calamities are mercies indeed to us when by them we find ourselves engaged to and enlarged in the service of God. They shall serve their own God, and neither be inclined, as they had been of old in the day of their apostasy, nor compelled, as they had been of late in the day of their captivity, to serve other gods. They shall serve David their king, such governors as God should from time to time set over them, of the line of David (as Zerubbabel), or at least sitting on the thrones of judgment, the thrones of the house of David, as Nehemiah. But certainly this has a further meaning. The Chaldee paraphrase reads it, They shall obey (or hearken to) the Messiah (or Christ), the Son of David, their king. To him the Jewish interpreters apply it. That dispensation which commenced at their return out of captivity brought them to the Messiah. He is called David their King because he was the Son of David (Mat 22:42) and he answered to the name, Mat 20:31, Mat 20:32. David was an illustrious type of him both in his humiliation and in his exaltation. The covenant of royalty made with David had principal reference to him, and in him the promises of that covenant had their full accomplishment. God gave him the throne of his father David; he raised him up unto them, set him upon the holy hill of Zion. God is often in the New Testament said to have raised up Jesus, raised him up as a King, Act 3:26; Act 13:23, Act 13:33. Observe, [1.] Those that serve the Lord as their God must also serve David their King, must give up themselves to Jesus Christ, to be ruled by him. For all men must honour the Son as they honour the Father, and come into the service and worship of God by him as Mediator. [2.] Those that are delivered out of spiritual bondage must make it appear that they are so by giving up themselves to the service of Christ. Those to whom he gives rest must take his yoke upon them.

But they shall serve the Lord their God,.... And him only, in a spiritual manner, in righteousness and true holiness, with reverence and godly fear; having respect to all his precepts and ordinances, and every branch of religious worship; joining themselves to Gospel churches, and worshipping along with them, before them, and in the midst of them; see Rev 3:9;

and David their king; not literally, who shall be raised up from the dead, and reign over them, which Kimchi supposes possible, though he does not assert it; nor his successors called by his name, as the kings of Egypt were called Pharaohs and Ptolemies, and the Roman emperors Caesars, of which we have no instance; nor were there any kings of David's line upon the throne of Israel after the Babylonish captivity, until the Messiah came, and who is the Person here meant; and so the Targum paraphrases it,

"and they shall hearken to, or obey, Messiah the son of David their king;''

and Kimchi owns that it may be interpreted of Messiah the son of David, whose name is called David, as it is in many prophecies, Eze 34:23; and this prophecy is understood of the Messiah by several Jewish writers (s); and in the Talmud (t) it is said,

"the holy blessed God will raise up unto thee another David; as it is said, "and they shall serve the Lord their God, and David their king, whom I will raise up unto them"; it is not said, "he hath raised up", but "I will raise up";''

and Christ is called David, not only because he is his son, but because he is his antitype. David was a type of Christ in his birth and parentage; the son of Jesse, born of mean parents, and at Bethlehem; in his outward form, ruddy and beautiful; in his inward character, a man of holiness, wisdom, and courage; in his offices of shepherd, prophet, and king; in his afflictions and sorrows, and in his wars and victories. The same Person is here meant as in the former clause, "the Lord their God"; since it is Jehovah that is here speaking; and he does not say "they shall serve me", but "the Lord their God"; and since the same service is to be yielded to David as to the Lord their God; and who is, in his divine nature, the Lord God, and so the object of all religious worship and service; and, in his human nature, of the seed of David; and by office a King, appointed by his Father, and owned by his people, as King of saints; so the words may be rendered, "they shall serve the Lord their God, even David their King"; see Tit 2:13;

whom I will raise up unto them; which is said of him in all his offices, Jer 23:5; and is expressive of his constitution as Mediator; and includes the Father's pitching upon him, appointing him, calling him, fitting and qualifying him, and sending him in the fulness of time, under this character, as a Mediator, Redeemer, and Saviour; all which was for the good of his people; as a favour to them, for their profit and advantage: his incarnation is for them; his obedience, sufferings, and death; his righteousness, and the salvation he wrought out; he is raised up, and sent to them to bless them, with all spiritual blessings that are in him, Act 3:26.

Instead of serving strangers (Jer 30:8), they shall serve the Lord, their rightful King in the theocracy (Eze 21:27).

David, their king--No king of David's seed has held the scepter since the captivity; for Zerubbabel, though of David's line, never claimed the title of "king." The Son of David, Messiah, must therefore be meant; so the Targum (compare Isa 55:3-4; Eze 34:23-24; Eze 37:24; Hos 3:5; Rom 11:25-32). He was appointed to the throne of David (Isa 9:7; Luk 1:32). He is here joined with Jehovah as claiming equal allegiance. God is our "King," only when we are subject to Christ; God rules us not immediately, but through His Son (Joh 5:22-23, Joh 5:27).

raise up--applied to the judges whom God raised up as deliverers of Israel out of the hand of its oppressors (Jdg 2:16; Jdg 3:9). So Christ was raised up as the antitypical Deliverer (Psa 2:6; Luk 1:69; Act 2:30; Act 13:23).
