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.
23. take thee—under My protection and to promote thee and thy people to honor (Ps 78:70).
a signet—(So 8:6; Jer 22:24). A ring with a seal on it; the legal representative of the owner; generally of precious stones and gold, &c., and much valued. Being worn on the finger, it was an object of constant regard. In all which points of view the theocratic people, and their representative, Zerubbabel the type, and Messiah his descendant the Antitype, are regarded by God. The safety of Israel to the end is guaranteed in Messiah, in whom God hath chosen them as His own (Isa 42:1; 43:10; 44:1; 49:3). So the spiritual Israel is sealed in their covenant head by His Spirit (2Co 1:20, 22; Eph 1:4, 13, 14). All is ascribed, not to the merits of Zerubbabel, but to God's gratuitous choice. Christ is the "signet" on God's hand: always in the Father's presence, ever pleasing in his sight. The signet of an Eastern monarch was the sign of delegated authority; so Christ (Mt 28:18; Joh 5:22, 23).
