Haggai delivers his fourth and final sermon. The date should be familiar: it's the same day as his previous sermon. He declares Zerubbabel, the governor of Judah, that the Lord will shake the heavens and the earth. Like the shaking of 2:6, Haggai declares war—God's Holy War against the heathens that will end in total victory. And for what purpose will the Lord do all this? The answer is in verse 23 – he will take Zerubbabel and make him his signet ring. The seal or signet ring was a symbol of authority. When the promise of the Messiah had been forgotten, Haggai reminds the people that Zerubbabel is in the line of Christ and focuses the promise of Christ's total victory "in that day" upon Zerubbabel. As the signet ring, David's "greater son" will rule, reign, and judge all the earth. To wrap up our series, we then turn back to the historical account in Ezra. After the people begin to rebuild the temple, they encounter persecution from the Persian governor, Tatnai. But this time, the people respond properly. Exhibiting courage following their repentance and the exhortations of Haggai and Zechariah, they declare, "we are the servants of the God of heaven and earth, and build the house." Rebuffed, Tatnai appeals to King Darius. Unlike his predecessor, Darius rules in favor of the Jews. He instructs their enemies to pay their expenses in building the temple. In other words, our story has a happy ending.
