12:3 I will make Yerushalayim a stone for all the peoples to lift
Zecharya prophesies about a future attack against Yehuda by the nations of the world. In that attack, the nations will besiege Yerushalayim, Israel’s capital, only to be miraculously defeated by Yehuda. Hashem states that Yerushalayim will become “a stone for all the peoples to lift,” and “all who lift it shall injure themselves.” In ancient times, when heavy stones lay in a field, the farmers would have to remove them with great effort, often cutting themselves futilely, in order to plough. This verse means that the nations of the world that try to remove Yehuda and Yerushalayim will fail, injuring themselves while trying to destroy the holy city. Spiritually, Yerushalayim and Yisrael symbolize God and His word. Taking on Yerushalayim forces the nations to contend with Hashem and His goodness. Ultimately, they will be blocked from going off on their own path.
