Zechariah 14:9; Zechariah 14:16-19

9 And the LORD will be king over all the earth. On that day there will be one LORD -- his name alone will be worshiped.
16 In the end, the enemies of Jerusalem who survive the plague will go up to Jerusalem each year to worship the King, the LORD Almighty, and to celebrate the Festival of Shelters. 17 And any nation anywhere in the world that refuses to come to Jerusalem to worship the King, the LORD Almighty, will have no rain. 18 And 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. 19 Egypt and the other nations will all be punished if they don't go to celebrate the festival.
