As you remember the substance of C-29, it is easy to see somewhat of a transition to this chapter, often considered a portion of what is known as the “Book of Consolation” with Jeremiah (chapter 30-33). In C-29, Jeremiah writes and exhorts the people in captivity to stay put and not fret. In this chapter there is a reminder concerning why they went into captivity (30:12-15), but a word of encouragement concerning what the Lord has planned for them in the coming days (3:18-22). Within this chapter there is a promise of a ruler (governor) that will come of the Davidic line (30:21, 9). Exactly who is in view is unstated. Many think Zerubbabel is view (see Haggai), but while others may see this to include him, there is something greater in view: “The immediate reference is to Zerubbabel and the elders who returned from the Captivity; but there is a larger significance than any merely human personage could exhaust or satisfactorily correspond to. There can be no doubt as to the Messianic character of this promise” (Pulpit Commentary). The Jewish Targum identifies this as Messianic also. “The Targum interprets these words of him; ‘their King shall be anointed from them, and their Messiah shall be revealed from the midst of them.’ And so it is applied to him in the Talmud (e), and in other writings of the Jews (f). Kimchi on the place says, ‘it is known that the King Messiah shall be of Israel’” (cited by John Gill, E-Sword).
