'Heir' in the Bible

And Cyrus, king of Persia, had Mithredath the treasurer bring them out, and he counted them out to Sheshbazzar, the governor (leader) of Judah.

then Zerubbabel the son of Shealtiel [heir to the throne of Judah] and Jeshua the son of Jozadak arose and began to rebuild the house of God in Jerusalem; and the prophets of God [Haggai and Zechariah] were with them, supporting and encouraging them.
