The prophet is instructed to perform a symbolic act to establish the leadership for those returning from exile. Using the silver and gold donated by the exiles for the building of God's house, he is told to forge physical symbols of authority. The prophet himself is tasked with taking these materials directly from the donors and crafting crowns [מצודת ציון, ביאור שטיינזלץ] with his own hands, rather than leaving the work to others [מלבי״ם]. Because two distinct metals are provided, two separate crowns are fashioned—one of silver and one of gold [מצודת דוד, רד״ק, מלבי״ם]. Some suggest that this entire event unfolds within a prophetic vision or through an angelic encounter [אבן עזרא].
Once the crowns are crafted, the focus shifts to Joshua, the High Priest. Placing a crown upon his head is akin to a royal coronation [אבן עזרא]. This act officially appoints him to his sacred role and serves as a lasting promise that the authority of the priesthood will remain with him and his descendants forever. It mirrors an earlier prophetic vision where a pure turban was placed upon his head as a sign of his spiritual standing [מצודת דוד, רד״ק].
The fate of the second crown is a matter of differing perspectives. One approach suggests that it is placed directly upon the head of Zerubbabel, the political leader of the people. Through this crowning, his status is effectively elevated from a mere governor to that of a true king [רד״ק]. However, an opposing view firmly maintains that only one crown is placed on Joshua, while the second is not worn by Zerubbabel at all [מלבי״ם]. According to this understanding, Joshua receives the silver crown, reflecting that the priesthood holds a lesser rank than the monarchy. The golden crown is instead set aside as a symbol of hope for the future redemption, waiting for the day when true kingship will return to the House of David. It is withheld from Zerubbabel because he does not yet serve as an active king, making a royal crown premature at that time [מצודת דוד].
