What are you, O great mountain? Before Zerubbabel you will become a plain. Then he will bring forth the capstone accompanied by shouts of ‘Grace, grace to it!’”

Commentary on Zechariah 4:7

• John Calvin (Reformed), Calvin's Commentaries on Zechariah 4:1-14: Chapter 4. Zechariah 4:1-6 1.

Antitypically, the antichristian last foe of Israel, the obstacle preventing her establishment in Palestine, about to be crushed before Messiah, is probably meant (Jer 51:25; Dan 2:34, Dan 2:44; Mat 21:44).
