The lawsuit, and the two evils
The book opens with God taking his own people to court. The charge sheet begins with what the marriage had been, 'I remember for thee the kindness of thy youth, the love of thine espousals; how thou wentest after me in the wilderness, in a land that was not sown' (2:2), and moves to the question a plaintiff asks: 'What unrighteousness have your fathers found in me, that they are gone far from me, and have walked after vanity, and are become vain?' (2:5). Then comes the verdict in one sentence with two counts. 'For my people have committed two evils: they have forsaken me, the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water' (2:13). The first count is leaving. The second is the substitute, and the image is exact: a cistern holds only what falls into it, and a cracked one loses even that. Calvin, working through this chapter, presses that the second evil is the folly that follows the first, since a man who leaves running water for a broken pit has wronged himself as well as God.

The word of Jehovah, and the man who could not put it down
Jeremiah's commission is given before he exists. 'Before I formed thee in the belly I knew thee, and before thou camest forth out of the womb I sanctified thee; I have appointed thee a prophet unto the nations' (1:5). He objects that he is a child; God touches his mouth and says 'Behold, I have put my words in thy mouth' (1:9), echoing the promise of Deuteronomy 18:18. Six verbs then set the terms of his whole ministry: 'to pluck up and to break down and to destroy and to overthrow, to build and to plant' (1:10). Those verbs come back at every hinge of the book, at the potter's house where they become the rule for every nation (18:7-9), over the good figs (24:6), in the new covenant chapter (31:28), to the remnant in the land (42:10), and to Baruch himself (45:4). What the word does to the prophet is described twice and both descriptions are physical. Eating it was joy: 'Thy words were found, and I did eat them; and thy words were unto me a joy and the rejoicing of my heart' (15:16). Holding it in was worse than speaking it: 'then there is in my heart as it were a burning fire shut up in my bones, and I am weary with forbearing, and I cannot contain' (20:9). And the word itself is described as force: 'Is not my word like fire? saith Jehovah; and like a hammer that breaketh the rock in pieces?' (23:29).

The heart, and why the law had to be moved inside
Jeremiah gives Scripture its sharpest sentence on the human interior: 'The heart is deceitful above all things, and it is exceedingly corrupt: who can know it?' (17:9). The next verse answers the question he just asked. 'I, Jehovah, search the mind, I try the heart, even to give every man according to his ways' (17:10). Nobody can read his own heart; God reads it. That diagnosis explains why the book keeps asking for something surgery-deep rather than ceremonial: 'Circumcise yourselves to Jehovah, and take away the foreskins of your heart' (4:4), a demand the book knows Judah cannot meet on its own, since 'Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good, that are accustomed to do evil' (13:23). Chapter 31 is the answer to chapter 17. If the trouble is inside, the law has to go inside: 'I will put my law in their inward parts, and in their heart will I write it' (31:33). Paul takes up the same image for the Corinthian church, an epistle 'written not with ink, but with the Spirit of the living God; not in tables of stone, but in tables that are hearts of flesh' (2 Corinthians 3:3).

The new covenant
The phrase 'new covenant' occurs once in the Old Testament, here: 'Behold, the days come, saith Jehovah, that I will make a new covenant with the house of Israel, and with the house of Judah' (31:31). It is defined against the covenant it replaces, 'which my covenant they brake, although I was a husband unto them' (31:32), and it carries four promises. The law goes inside a person instead of onto stone. The old covenant formula stands unchanged, 'and I will be their God, and they shall be my people' (31:33), the same words already spoken at 7:23, and spoken again at 30:22 with its clauses in the reverse order, 'ye shall be my people, and I will be your God', so the new covenant keeps the goal the first one had. Knowledge of God becomes universal within it: 'they shall all know me, from the least of them unto the greatest of them' (31:34). And underneath all three lies forgiveness of a particular kind, 'for I will forgive their iniquity, and their sin will I remember no more' (31:34). Two things about the wording matter and are often passed over. The covenant is announced to Israel and Judah by name, and the New Testament writers who apply it to the church never take it away from them; Paul asks 'Did God cast off his people? God forbid' and answers 'God did not cast off his people which he foreknew' (Romans 11:1-2). And the promise is future in Jeremiah's mouth. Jesus makes it present at the table: 'This cup is the new covenant in my blood, even that which is poured out for you' (Luke 22:20).

Babylon called my servant, and the seventy years
The hardest thing Jeremiah had to say was that the invading pagan empire was working for God. Twice Nebuchadnezzar is given the title reserved elsewhere for Moses and David: 'I will send unto Nebuchadrezzar the king of Babylon, my servant' (25:9), and again, 'And now have I given all these lands into the hand of Nebuchadnezzar the king of Babylon, my servant' (27:6). From that follows the counsel that got him charged with treason, since surrender was obedience and resistance was rebellion against God rather than only against Babylon. The instrument is on a clock. 'these nations shall serve the king of Babylon seventy years' (25:11), and when the term runs out the instrument is judged in its turn: 'when seventy years are accomplished, that I will punish the king of Babylon, and that nation' (25:12), which chapters 50 and 51 then spell out at length. To the exiles already there the same number arrives as mercy: 'After seventy years are accomplished for Babylon, I will visit you, and perform my good word toward you, in causing you to return to this place' (29:10), followed by the sentence most often quoted out of its setting, 'thoughts of peace, and not of evil, to give you hope in your latter end' (29:11). It was spoken to people who would spend the rest of their lives in Babylon, and it held anyway.

The promise to Israel that outlasts the exile
Jeremiah announces the end of the nation and in the same book forecloses the idea that God is finished with it. He puts the guarantee where nobody can move it, in the fixed order of creation. God 'giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night' (31:35), and then: 'If these ordinances depart from before me, saith Jehovah, then the seed of Israel also shall cease from being a nation before me for ever' (31:36). He says it a second time from the other direction, 'If heaven above can be measured, and the foundations of the earth searched out beneath, then will I also cast off all the seed of Israel for all that they have done' (31:37), and a third time in chapter 33, where the covenant of day and night stands as surety for the seed of Jacob and of David (33:25-26). The affection behind the guarantee is stated plainly, 'Yea, I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee' (31:3), and again over the northern tribes long since deported, 'therefore my heart yearneth for him; I will surely have mercy upon him' (31:20). Reading the church into these promises so that Israel loses them runs against the text and against Romans 11, and this site does not teach it. The new covenant Jeremiah announces is offered to the world through Christ, and the people it was announced to are still the people it was announced to.
