Literary Context
This verse functions as a short closing praise after the promises and images in Zechariah 9 about God acting for his people and bringing security and renewed life. It reads like a final, summarized response to what has just been described: because God will act, the fitting reaction is awe at his character, and the expected result is abundance. The logic moves from worship (“how great…”) to visible effects (“grain… new wine…”). As an ending line, it leaves the reader with a picture of thriving community life.
