The Surviving Nations Come Up to Worship at the Feast of Booths
Not all the nations are simply destroyed. Survivors from those that came against Jerusalem now go up year after year to worship the King, the LORD of hosts, and to keep the Feast of Booths. Refusal brings withheld rain and plague. Judgment therefore gives way to a startling picture: former enemies become pilgrims.
Where this fits in the story: the nations-at-Zion hope appeared earlier in Zechariah 2 and 8. Here it reaches the book’s climax. Israel’s festival calendar becomes the prophetic language for worldwide acknowledgment of the LORD as King.
Competing interpretations: some Christian traditions expect a literal future international observance of Sukkot; others understand Israel’s feast imagery as the prophetic form of universal worship in the consummated kingdom. The NT does not explicitly settle every calendar mechanic.
