Isaiah 62:3

62:3 You will be a majestic crown in the hand of the Lord,

a royal turban in the hand of your God.

Haggai 2:23

2:23 On that day,’ ¹  says the Lord who rules over all, ‘I will take you, Zerubbabel son of Shealtiel, my servant,’ ²  says the Lord, ‘and I will make you like a signet ring, ³  for I have chosen you,’ says the Lord who rules over all.” ⁴ 

[2:23]  ¹ sn The expression on that day appears as a technical eschatological term in a number of other OT passages (cf., e.g., Isa 2:11, 17, 20; 3:7, 18; Amos 8:3, 9; Hos 2:18, 21).

[2:23]  ² sn My servant. The collocation of “servant” and “chosen” bears strong messianic overtones. See the so-called “Servant Songs” and other messianic texts in Isaiah (Isa 41:8; 42:1; 44:4; 49:7).

[2:23]  ³ sn The noun signet ring, used also to describe Jehoiachin (Jer 22:24-30), refers to a ring seal worn by a king or other important person and used as his signature. Zerubbabel was a grandson of King Jehoiachin (1 Chr 3:17-19; Matt 1:12); God once pronounced that none of Jehoiachin’s immediate descendants would rule (Jer 22:24-30), but here he reverses that judgment. Zerubbabel never ascended to such a lofty position of rulership; he is rather a prototype of the Messiah who would sit on David’s throne.

[2:23]  ⁴ tn The repetition of the formula “says the Lord who rules over all” in v. 23 emphasizes the solemn and divine nature of the promise.
