This chapter contains a prophecy of the call and conversion of the Jews in the latter day; which being a matter of moment and importance, and that it might continue, and be read hereafter, it is ordered to be written in a book, Jer 30:1,2; the thing itself is expressed by a return from captivity to their own land, Jer 30:3; but previous to this there would be most dreadful times, as never were the like, Jer 30:4-7; yet there would be a deliverance from them, and from the yoke of the oppressor; when the Jews should serve the Lord God, and the true Messiah, Jer 30:8,9; of which deliverance and salvation they are assured in the strongest terms, though all other nations should be made an end of, among whom they were, Jer 30:10,11; and though their ease might seem to be desperate, Jer 30:12-17; nevertheless they should be brought into a very comfortable and happy estate; their city rebuilt; their offspring increased; and religious worship established; and, above all, the Messiah should be made known to them as their King and Priest, and they appear to be the Lord's covenant people, Jer 30:18-22; and the chapter is concluded with threatening utter destruction to the wicked, Jer 30:23,24.
