Zakharia 6:13

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 ¹  with him on his throne and they will see eye to eye on everything.

Zakharia 14:21

14:21 Every cooking pot in Jerusalem and Judah will become holy in the sight of the Lord who rules over all, so that all who offer sacrifices may come and use some of them to boil their sacrifices in them. On that day there will no longer be a Canaanite ²  in the house of the Lord who rules over all.

[6:13]  ¹ 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).

[14:21]  ² tn Or “merchant”; “trader” (because Canaanites, especially Phoenicians, were merchants and traders; cf. BDB 489 s.v. I and II כְּנַעֲנִי). English versions have rendered the term as “Canaanite” (KJV, NKJV, NASB, NIV), “trader” (RSV, NEB), “traders” (NRSV, NLT), or “merchant” (NAB), although frequently a note is given explaining the other option. Cf. also John 2:16.

[14:21]  sn This is not to preclude the Canaanite (or anyone else) from worship; the point is that in the messianic age all such ethnic and religious distinctions will be erased and all people will be eligible to worship the Lord.
