In Jeremiah. 27-29 we see with what energy, and yet thoughtfulness, Jeremiah enforced the lessons of Jeremiah. 25. These chapters belong to the first four years of Zedekiah.
The spelling of certain proper names in these chapters has led some to argue that they were revised and corrected in Ezra's time, if not by Ezra himself. Others think the fact of no importance whatever.

Ambassadors being come from several neighboring nations to solicit the king of Judah to join in a confederacy against the king of Babylon, Jeremiah is commanded to put bands and yokes upon his neck, (the emblems of subjection and slavery), and to send them afterwards by those ambassadors to their respective princes; intimating by this significant type that God had decreed their subjection to the Babylonian empire, and that it was their wisdom to submit. It is farther declared that all the conquered nations shall remain in subjection to the Chaldeans during the reign of Nebuchadnezzar, and those of his son and grandson, even till the arrival of that period in which the Babylonians shall have filled up the measure of their iniquities; and that then the mighty Chaldean monarchy itself, for a certain period the paramount power of the habitable globe, shall be voted with a dreadful storm of Divine wrath, through the violence of which it shall be dashed to pieces like a potter's vessel, the fragments falling into the hands of many nations and great kings, Jeremiah 27:1-11. Zedekiah, particularly, is admonished not to join to the revolt against Nebuchadnezzar, and warned against trusting to the suggestions of false prophets, Jeremiah 27:11-18. The chapter concludes with foretelling that what still remained of the sacred vessels of the temple should be carried to Babylon, and not restored till after the destruction of the Chaldean empire, Jeremiah 27:19-22.

INTRODUCTION TO JEREMIAH 27
This chapter contains a prophecy of the subjection of the king of Judah, with five neighbouring kings, to the king of Babylon; signified by bonds and yokes on the prophet's neck, which they are exhorted patiently to bear, as being most for their good; and not to give heed to false prophets, who would persuade them to the contrary. The date of the prophecy is in Jeremiah 27:1; the order to make the yokes, and send them to the several neighbouring princes by their messengers at Jerusalem, Jeremiah 27:2; what they should say to their masters from the God of Israel, who is described from his power in the creation of the earth, and the disposal of it, Jeremiah 27:4; as that he had given all their lands into the hand of the king of Babylon, whom they should serve, or it would be worse for them, Jeremiah 27:6; and therefore should not hearken to their prophets, who prophesied lies; if they did, it would be to their hurt; whereas, if they quietly submitted, they would dwell in their own land, Jeremiah 27:9; particularly Zedekiah king of Judah is exhorted to submit; and both he, and the priests and the people, are advised not to hearken to the false prophets, Jeremiah 27:12; particularly as to what they said concerning the speedy return of the vessels of the temple, which were carried away to Babylon; but might assure themselves they should remain there; and the rest also should be taken, and not returned until the end of the seventy years, Jeremiah 27:16.

(Jeremiah 27:1-11) The neighbouring nations to be subdued.
(Jeremiah 27:12-18) Zedekiah is warned to yield.
(Jeremiah 27:19-22) The vessels of the temple to be carried to Babylon, but afterwards to be restored.

The Yoke of Babylon upon Judah and the Neighbouring Peoples - Jeremiah 27-29
These three chapters are closely connected with one another. They all belong to the earlier period of Zedekiah's reign, and contain words of Jeremiah by means of which he confirms and vindicates against the opposition of false prophets his announcement of the seventy years' duration of the Chaldean supremacy over Judah and the nations, and warns king and people patiently to bear the yoke laid on them by Nebuchadnezzar. The three chapters have besides an external connection. For Jeremiah 28 is attached to the event of Jeremiah 27 by its introductory formula: And it came to pass in that year, at the beginning, etc., as Jeremiah 29 is to Jeremiah 28 by ואלּה. To this, it is true, the heading handed down in the Masoretic text is in contradiction. The date: In the beginning of the reign of Jehoiakim, the son of Josiah king of Judah, came this word to Jeremiah (Jeremiah 27:1), is irreconcilable with the date: And it came to pass in that year, in the beginning of the reign of Zedekiah king of Judah, in the fourth year, in the fifth month. The name "Jehoiakim the son of Josiah" in Jeremiah 27:1 is erroneous. It is without doubt the blunder of a copyist who had in his mind the heading of the 26th chapter, and should have been "Zedekiah;" for the contents of Jeremiah 27 carry us into Zedekiah's time, as plainly appears from Jeremiah 27:3, Jeremiah 27:12, and Jeremiah 27:20. Hence the Syr. translation and one of Kennicott's codd. have substituted the latter name.
(Note: Following the example of ancient comm., Haevernick in his Introd. (ii. 2) has endeavoured to defend the date: "In the beginning of the reign of Jehoiakim the son of Josiah." To this end he ventures the hypothesis, that in Jeremiah 27 there are placed beside one another three discourses agreeing in their subject-matter: "one addressed to Jehoiakim (Jeremiah 27:2-11), a second to Zedekiah (Jeremiah 27:12-15), a third to the priests and people;" and that the words: "by the hand of the ambassador that came to Zedekiah the king of Judah," are appended to show how Zedekiah ought to have obeyed the older prophecy of Jehoiakim's time, and how he should have borne himself towards the nations with which he was in alliance. but this does not solve the difficulty. The prophecy, Jeremiah 27:4-11, is addressed to the kings of Edom, Moab, Ammon, Tyre, and Sidon; but since the envoys of these kings did not come to Jerusalem till Zedekiah's time, we are bound, if the prophecy dates from the beginning of Jehoiakim's reign, to assume that this prophecy was communicated to Jeremiah and published by him eleven years before the event, upon occasion of which it was to be conveyed to the kings concerned. An assumption that would require unusually cogent reasons to render it credible. Vv. 4b-21 contain nothing whatever that points to Jehoiakim's time, or give countenance to the hypothesis that the three sections of this chapter contain three discourses of different dates, which have been put together on account merely of the similarity of their contents.
Beyond this one error of transcription, these three chapters contain nothing that could throw any doubt on the integrity of the text. There are no traces of a later supplementary revision by another hand, such as Mov., Hitz., and de W. profess to have discovered. The occurrence of Jeremiah's name in the contracted form ירמיה, as also of other names compounded with Jahu in the form Jah, does not prove later retouching; for, as Graf has shown, we find alongside of it the fuller form also (Jeremiah 28:12; Jeremiah 29:27-30), and have frequently both longer and shorter forms in the same verse (so in Jeremiah 27:1; Jeremiah 28:12; Jeremiah 29:29-31). And so long as other means for distinguishing are wanting, it will not do to discriminate the manner of expression in the original text from that of the reviser by means of these forms alone. Again, as we have shown at p. 194, note, there is a good practical reason for Jeremiah's being called "the prophet" (הנּביא); so that this too is not the reviser's work. Finally, we cannot argue later addition from the fact that the name of the king of Babylon is written Nebuchadnezzar in Jeremiah 27:6, Jeremiah 27:8,Jeremiah 27:20; Jeremiah 28:3, Jeremiah 28:11, Jeremiah 28:14; Jeremiah 29:1, Jeremiah 29:3; for the same form appears again in Jeremiah 34:1 and Jeremiah 39:5, and with it we have also Nebuchadrezzar in Jeremiah 29:21 and Jeremiah 39:1. Elsewhere, it is true, we find only the one form Nebuchadnezzar, and this is the unvarying spelling in the books of Kings, Chron., Ezra, Daniel., and in Esther 2:6; whereas Ezekiel uniformly writes Nebuchadrezzar (Ezekiel 26:7; Ezekiel 29:18-19, and Ezekiel 30:10), and this form Jeremiah uses twenty-seven times (Jeremiah 21:2, Jeremiah 21:7; Jeremiah 22:25; Jeremiah 24:1; Jeremiah 25:1, Jeremiah 25:9; Jeremiah 29:21; Jeremiah 32:1, Jeremiah 32:28; Jeremiah 35:11; Jeremiah 37:1; Jeremiah 39:1, Jeremiah 39:11; Jeremiah 43:10; Jeremiah 44:30; Jeremiah 46:2, Jeremiah 46:13, Jeremiah 46:26; Jeremiah 49:28, 40; Jeremiah 50:17; Jeremiah 51:34; Jeremiah 52:4, Jeremiah 52:12, Jeremiah 52:28-30 - not merely in the discourses, but in the headings and historical parts as well). But though the case is so, we are not entitled to conclude that Nebuchadnezzar was a way of pronouncing the name that came into use at a later time; the conclusion rather is, as we have remarked at p. 203, and on Daniel 1:1, that the writing with n represents the Jewish-Aramaean pronunciation, whereas the form Nebuchadrezzar, according to the testimony of such inscriptions as have been preserved, expresses more fairly Assyrian pronunciation. The Jewish way of pronouncing would naturally not arise till after the king of Babylon had appeared in Palestine, from which time the Jews would have this name often on their lips. Hence it is in the book of Jeremiah alone that we find both forms of the name (that with r 27 times, that with n 10 times). How it has come about that the latter form is used just three times in each of Jeremiah 27 and 28 cannot with certainty be made out. But note, (1) that the form with n occurs twice in 28 (Jeremiah 28:3 and Jeremiah 28:11) in the speech of the false prophet Hananiah, and then, Jeremiah 28:14, in Jeremiah's answer to that speech; (2) that the prophecy of Jeremiah 27 was addressed partly to the envoys of the kings of Edom, Moab, Ammon, and Phoenicia, while it is partly a warning to the people against the lying speeches of the false prophets, and that it is just in these portions, Jeremiah 27:6, Jeremiah 27:8, and Jeremiah 27:20, that the name so written occurs. If we consider this, we cannot avoid the conjecture, that by changing the r for n, the Jewish people had accommodated to their own mode of utterance the strange-sounding name Nabucudurusur, and that Jeremiah made use of the popular pronunciation in these two discourses, whereas elsewhere in all his discourses he uses Nebucahdrezzar alone; for the remaining cases in which we find Nebuchadnezzar in this book are contained in historical notices.)
