Yahweh came directly to Zechariah. He told him that Zerubbabel, the governor of Judah, would lay the foundation for the house of Yahweh with his own hands. Then Zerubbabel would complete the Temple also. Thus, they would know that Yahweh of hosts had sent him to them. Those that despised the little things would rejoice when they would see the plummet or the measuring line in Governor Zerubbabel’s hands.
Yahweh said that Zerubbabel, the governor of Judah, would have a special role in the new kingdom of Israel. Yahweh was going to shake up heaven and earth. He was going to overthrow all the kingdoms and countries on the earth. All the chariots, with their riders, as well as the cavalry with their horses would all fall. Zerubbabel, the servant of Yahweh, would have a signet ring because Yahweh had chosen him. His grandfather would have been a king as part of the Davidic lineage
The rulers and the remaining people of Jerusalem gathered to hear the voice of Yahweh, via the prophet Haggai. This included the governor of Judah, Zerubbabel, and the high priest Joshua, as mentioned earlier. They would obey Haggai as the voice of Yahweh, since they feared Yahweh. Yahweh had sent them Haggai as a prophet to speak in his name.
Zerubbabel was the governor of Judah appointed by the Persian King Darius I, thus ending the Babylonian captivity, sometime between 538-520 BCE. He was the grandson of one of the last kings of Judah, King Jehoiachin. In this new role, he was actually an official governor in the Persian state for the area of Judah, but he was born and raised in Babylon. He along with Jeshua began to rebuild the Temple in Jerusalem. There is some confusion with the name of Sheshbazzar, who either was his uncle or another name for him. Some hold that Sheshbazzar was appointed by King Cyrus as the governor of Judah in 538 BCE. Then King Darius I named Zerubbabel. Both are mentioned in the Book of Ezra, chapter 2. Zerubbabel was also mentioned by the Minor Prophets, Haggai and Zechariah. Finally, there is the idea of the signet ring. Does it apply to temporal power or the restored power of Yahweh? Interesting enough, Sirach does not mention Ezra at all among his famous men.
