Sefer Zerubavel, also called the Book of Zerubbabel or the Apocalypse of Zerubbabel, is a medieval Hebrew apocalypse written at the beginning of the 7th century CE in the style of biblical visions placed into the mouth of Zerubbabel, the last descendant of the Davidic line to take a prominent part in Israel's history, who laid the foundation of the Second Temple in the 6th century BCE.
