The Branch is a title for the Messiah (see Zechariah 3:8), whom Jeshua represents.
build the temple of the LORD: Jeshua the high priest helped build the temple in Jerusalem (Ezra 3:1–2, 8–9; 5:2). Similarly, Jesus the Messiah would build the eternal heavenly temple through his death, burial, and resurrection (John 2:19–22; 4:23–24; Ephesians 2:19–22; Hebrews 8:1–2).
The Messiah would rule as king, a role linked to David and the tribe of Judah (2 Samuel 7:12–16).
He will be a priest on His throne: The Messiah’s priestly role is linked to Aaron and the tribe of Levi (Exodus 29:44).
Jeshua’s crown represents his two roles. Melchizedek also had the dual roles of priest and king (Genesis 14:17–20), as does the Messiah (Psalm 110:4; Hebrews 7:1–3, 15–17).
