Passage
And every pot in Jerusalem and in Judah will be holy to Yahweh of hosts; and all who sacrifice will come and take of them and boil in them. And there will no longer be a Canaanite in the house of Yahweh of hosts in that day.
And every pot in Jerusalem and in Judah will be holy to Yahweh of hosts; and all who sacrifice will come and take of them and boil in them. And there will no longer be a Canaanite in the house of Yahweh of hosts in that day.
Zechariah 14:19 This will be the punishment of Egypt, and the punishment of all the nations who do not go up to celebrate the Feast of Booths.
Zechariah 14:20 In that day there will be inscribed on the bells of the horses, “Holy to Yahweh.” And the pots in the house of Yahweh will be like the bowls before the altar.
Zechariah 14:21 And every pot in Jerusalem and in Judah will be holy to Yahweh of hosts; and all who sacrifice will come and take of them and boil in them. And there will no longer be a Canaanite in the house of Yahweh of hosts in that day.
The verse centers on "jerusalem", "judah", "holy", "yahweh", "hosts", "sacrifice", "come", and "take". It is saying that the verse draws attention to "jerusalem" and "judah", so its meaning should be read from those terms before moving to application.
The prior verse says "In that day there will be inscribed...", giving immediate footing for "jerusalem" and "judah". In Zechariah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "jerusalem" and "judah" with trust shaped by these words, not by a vague optimism outside the passage.
