Each author had his own views on whether Jeremiah’s prophecies failed.

Jeremiah 22, for example, crushes the hope of a continued Davidic lineage. IF Coniah were a signet ring, YHWH would cast him off. this is followed by Coniah being called childless, with no one to sit on the throne.
Yet the prophet Haggai calls Zerubbabel the son of Shealtiel (son of Coniah) the signet ring. this is a direct answer to Jeremiah, probably in contradiction.
Jeremiah 23 and 33, YHWH promises to raise a branch to David named “YHWH is our righteousness” – a phrase. Zechariah matches the two promises by crowning a branch twice, Jesus son of “YHWH is righteous.” While ‘raising a branch’ usually means a direct descendant, in this case it seems Zechariah means to replace the kingly line. Zechariah 3 seems to have Jesus imitate the scene in Jeremiah (52?, 39?) where Jeconiah is taken out of prison, given royal robes, and allowed to eat at the king’s table (raised among his peers).
2 Chronicles 36 and Ezra 1 consider Jeremiah’s 70 year sabbath to be completed by Cyrus’s edict, only 47 years after Nebuchadnezzar destroyed Jerusalem. However, by the time Nehemiah comes along, he sems inclined to think the Judeans are slaves to Persia. There needs to be some sort of remedy. The people sign a NEW TESTAMENT, and in his last chapter he runs two of Jesus’s descendants out of powerful positions in Jerusalem. However, there is not indication that Jeremiah’s prophecies had not come true in Nehemiah’s eyes.

Only Daniel seems to be at odds with the 70 weeks, extending it to 490 or something similar. Yet if 2 Chronicles 36 and Ezra 1 can equate 47 years with 70 and call the prophecy fulfilled, are we really to think so literally about Daniel’s ‘extension’? Perhaps he intended only to promote the new sanctification of the temple in 168 (?) BCE.
