Then Haggai, the LORD's messenger, gave the people this message from the LORD: "I am with you, says the LORD!"
So the LORD sparked the enthusiasm of Zerubbabel son of Shealtiel, governor of Judah, Jeshua son of Jehozadak, the high priest, and the whole remnant of God's people. They came and began their work on the house of the LORD Almighty, their God.
This was on September 21 of the second year of King Darius's reign.
