Speak to Zerubbabel, governor of Judah, saying, I {m} will shake the heavens and the earth;

(m) I will make a change, and renew all things in Christ, of whom Zerubbabel is here a figure.

Jamieson-Fausset-Brown Bible Commentary

21. to Zerubbabel-Perhaps Zerubbabel had asked as to the convulsions foretold (Hag 2:6, 7). This is the reply: The Jews had been led to fear that these convulsions would destroy their national existence. Zerubbabel, therefore, as their civil leader and representative is addressed, not Joshua, their religious leader. Messiah is the antitypical Zerubbabel, their national Representative and King, with whom God the Father makes the covenant wherein they, as identified with Him, are assured of safety in God's electing love (compare Hag 2:23, "will make thee as a signet"; "I have chosen thee").

shake . heavens-(see on [1172]Hag 2:6, 7); violent political convulsions accompanied with physical prodigies (Mt 24:7, 29).

Matthew Henry's Concise Commentary

2:20-23 The Lord will preserve Zerubbabel and the people of Judah, amidst their enemies. Here is also foretold the establishment and continuance of the kingdom of Christ; by union with whom his people are sealed with the Holy Ghost, sealed with his image, thus distinguished from all others. Here also is foretold the changes, even to that time when the kingdom of Christ shall overthrow and occupy the place of all the empires which opposed his cause. The promise has special reference to Christ, who descended from Zerubbabel in a direct line, and is the sole Builder of the gospel temple. Our Lord Jesus is the Signet on God's right hand, for all power is given to him, and derived from him. By him, and in him, all the promises of God are yea and amen. Whatever changes take place on earth, all will promote the comfort, honour, and happiness of his servants.
