This important message comes with Zechariah’s eighth vision (Zechariah 6:1–8). Jeshua’s symbolic crowning as both king and priest was not a real political setup for Judah. It likely represents the coming of the Messiah, God's chosen king.
In Zechariah, the Branch is a title for this coming Messiah. The image describes new growth from what seemed dead, like a shoot growing from a cut-down tree. This shows that, even after exile and failure, God will raise up a new ruler from David’s line. The Branch will build the temple of the Lord and unite kingship and priesthood in one person (Zechariah 6:12; compare 3:8).
