In the end, the enemies of Jerusalem who survive the plague will go up to Jerusalem each year to worship the King, the LORD of Heaven’s Armies, and to celebrate the Festival of Shelters.
Any nation in the world that refuses to come to Jerusalem to worship the King, the LORD of Heaven’s Armies, will have no rain.
If the people of Egypt refuse to attend the festival, the LORD will punish them with the same plague that he sends on the other nations who refuse to go.
References for Zechariah 14:18
Egypt and the other nations will all be punished if they don’t go to celebrate the Festival of Shelters.
On that day even the harness bells of the horses will be inscribed with these words: HOLY TO THE LORD . And the cooking pots in the Temple of the LORD will be as sacred as the basins used beside the altar.
In fact, every cooking pot in Jerusalem and Judah will be holy to the LORD of Heaven’s Armies. All who come to worship will be free to use any of these pots to boil their sacrifices. And on that day there will no longer be traders in the Temple of the LORD of Heaven’s Armies.
