In the earlier part of the chapter, God gives Jeremiah a prophetic message to prove that it came from God. In the first part of the message, God speaks of Jerusalem’s capture and destruction.
Then, the message of the prophecy changes.
36 And now therefore thus saith Jehovah, the God of Israel, concerning this city, whereof ye say, It is given into the hand of the king of Babylon by the sword, and by the famine, and by the pestilence:
37 Behold, I will gather them out of all the countries, whither I have driven them in mine anger, and in my wrath, and in great indignation; and I will bring them again unto this place, and I will cause them to dwell safely:
38 and they shall be my people, and I will be their God:
39 and I will give them one heart and one way, that they may fear me for ever, for the good of them, and of their children after them:
40 and I will make an everlasting covenant with them, that I will not turn away from following them, to do them good; and I will put my fear in their hearts, that they may not depart from me.
41 Yea, I will rejoice over them to do them good, and I will plant them in this land assuredly with my whole heart and with my whole soul.
42 For thus saith Jehovah: Like as I have brought all this great evil upon this people, so will I bring upon them all the good that I have promised them.
43 And fields shall be bought in this land, whereof ye say, It is desolate, without man or beast; it is given into the hand of the Chaldeans.
44 Men shall buy fields for money, and subscribe the deeds, and seal them, and call witnesses, in the land of Benjamin, and in the places about Jerusalem, and in the cities of Judah, and in the cities of the hill-country, and in the cities of the lowland, and in the cities of the South: for I will cause their captivity to return, saith Jehovah.
Is there really anything more to say?
Before, there was judgement and condemnation.
Now there is bright hope and everlasting blessing.
There was darkness.
Now there is light.
