Zechariah 6:12-13

6:12 Then say to him, ‘The Lord who rules over all says, “Look – here is the man whose name is Branch, ¹  who will sprout up from his place and build the temple of the Lord. 6:13 Indeed, he will build the temple of the Lord, and he will be clothed in splendor, sitting as king on his throne. Moreover, there will be a priest ²  with him on his throne and they will see eye to eye on everything.

[6:12]  ¹ tn The epithet “Branch” (צֶמַח, tsemakh) derives from the verb used here (יִצְמָח, yitsmakh, “will sprout up”) to describe the rise of the Messiah, already referred to in this manner in Zech 3:8 (cf. Isa 11:1; 53:2; Jer 33:15). In the immediate context this refers to Zerubbabel, but the ultimate referent is Jesus (cf. John 19:5).

[6:13]  ² sn The priest here in the immediate context is Joshua but the fuller and more distant allusion is to the Messiah, a ruling priest. The notion of the ruler as a priest-king was already apparent in David and his successors (Pss 2:2, 6-8; 110:2, 4), and it finds mature expression in David’s greater Son, Jesus Christ, who will combine both offices in his kingship (Heb 5:1-10; 7:1-25).
