Anchor Text: Zech 6:12-13 — The Branch Priest-King
Significance: Jeremiah 23:5-6 is the first text to make the Branch explicitly Davidic and royal: "I will raise up for David a righteous Branch (ṣemaḥ ṣaddîq), and He will reign wisely as King... and this is His name by which He will be called: The LORD Our Righteousness." Zechariah 6:12-13 takes up Jeremiah's ṣemaḥ and brings it to its climactic naming and enthronement: "Here is a man whose name is the Branch... He will sit on His throne and rule. And He will be a priest on His throne." Jeremiah supplies the royal-and-righteous Branch with the divine name; Zechariah adds the decisive new element — the same Branch is also a priest, reuniting in one figure the two offices Israel's order kept apart. The connection is Promise-Fulfillment within the canon, developed along the Davidic-Branch Longitudinal Theme: Zechariah does not merely repeat Jeremiah but escalates him, fusing the royal Branch of Jer 23 with priestly office and temple-building work. The telos: the Branch is "righteous" not as a distant ideal but as the One who is "The LORD Our Righteousness" — so that the trajectory ends not in admiring a perfect king from afar but in receiving Him as the believer's own righteousness, a Christ to be desired because in Him justice and salvation meet.
