Zerubbabel and the Davidic Line
The Davidic line from Jeconiah had been cursed by Jer. 22:30). Zerubbabel was of the main Davidic line through Solomon and Jeconiah.
The prophets Zechariah and Haggai both give unclear statements regarding Zerubbabel's authority in their oracles, in which Zerubbabel was either the subject of a false prophecy or the receiver of a divine promotion to kingship. He could also be viewed as a governor of a state within another nation and thus technically "not on the throne" of a nation. Either way, he was given the task of rebuilding the Temple in the second year of the reign of Darius I (520 BC), along with the high priest Joshua son of Jehozadak.
Muslim historian Ya'qubi attributed the recovery of the Torah and the Books of the Prophets to him instead of Ezra. The Seder Olam Zutta lists him as the Exilarch in Babylon to succeed Shealtiel. The texts are conflicting as to whether Zerubbabel was the son of Shealtiel or his nephew. His son Meshullam succeeded him as Exilarch, and was followed by another son Hananiah. His other sons were Hashubah, 1 Chronicles 3:19).
