Haggai 2:23

“In that day, saith the Lord of hosts, etc.] When all these kingdoms, and their thrones and strength, are destroyed; which shows that what follows cannot be understood literally of Zerubbabel, who lived not to see these things done: will I take thee, O Zerubbabel my servant, the son of Shealtiel, saith the Lord; that is, the Messiah, as is owned by Abarbinel; who saysf45, “the King Messiah shall come, who is of the seed of Zerubbabel; and he shall be the seal of the structure, and the end of the kingdoms; as it is said, “I will make thee as a signet, for I have chosen thee, saith the Lord of hosts”; for this no doubt is said concerning the days of the Messiah:” and another Jewish writerf46,…”

“take thee--under My protection and to promote thee and thy people to honor (Psa 78:70). a signet-- (Sol 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; Isa 43:10; Isa 44:1; Isa 49:3). So the spiritual Israel is sealed in their covenant head by His Spirit (Co2 1:20, Co2…”

“I will make thee as a signet - God reverses to Zerubbabel the sentence on Jeconiah for his impiety. To Jeconiah He had said Jeremiah 22:24, “though he were the signet upon My right hand, yet would I pluck thee thence; and I will give thee into the hand of them that seek thy life.” The signet was very precious to its owner, never parted with, or only to those to whom authority was delegated (as by Pharaoh to Joseph Genesis 41:42, or by Ahasuerus to Haman Esther 3:10 and then to Mordecai Esther 8:2.); through it his will was expressed. Hence, the spouse in the Canticles says, Song of Solomon 8:6. “Set me, as a seal upon thy heart, as a seal upon thy arm.” The signet also was an ornament to him…”

“My servant - A type of him who was God's most beloved servant. As a signet - Which is very highly valued, and carefully kept. So shall the antitypical Zerubbabel, the Messiah, be advanced, loved, and inviolably preserved king, and supreme over his church. He is indeed the signet on God's right - hand. For all power is given to him, and derived from him. In him the great charter of the gospel is signed, and sanctified, and it is in him, that all the promises of God are yea and amen.

“2:23 The signet ring was a symbol of kingship. An engraved stone set in a gold or silver finger ring was used to seal or endorse official documents. The image here emphasizes the divine authority invested in Zerubbabel and assures the people of God’s continuing involvement in the political process (despite the failures of the Hebrew monarchs). The designation of Zerubbabel as the signet of the Lord no doubt rekindled expectations for the Messiah, since Zerubbabel was a descendant of King David. Yet the declaration ultimately points beyond Zerubbabel (see study note on 2:21) to one of his descendants (see Matt 1:12; Luke 1:32-33; 3:27).”

“O Zerubbabel: It seems evident that the Messiah is here described under the name of Zerubbabel, as elsewhere under that of David, whose kingdom, after these mighty convulsions, should supersede all others. and will: Sol 8:6; Jer 22:24; Joh 6:27; Ti2 2:19 for: Isa 42:1, Isa 43:10, Isa 49:1-3; Zac 4:6-14; Mat 12:18; Pe1 2:4 Next: Zechariah Chapter 1”
