Zechariah 14:16

14:16 Then all who survive from all the nations that came to attack Jerusalem will go up annually to worship the King, the Lord who rules over all, and to observe the Feast of Tabernacles.

Zechariah 14:18

14:18 If the Egyptians will not do so, they will get no rain – instead there will be the kind of plague which the Lord inflicts on any nations that do not go up to celebrate the Feast of Tabernacles.

sn Having imposed his sovereignty over the earth following the Battle of Armageddon, the Lord will receive homage and tribute from all who survive from all the nations. The Feast of Tabernacles was especially associated with covenant institution and renewal so it will be appropriate for all people to acknowledge that they are vassals to the Lord at that time (cf. Deut 31:9-13; Neh 8:12-18; 9:1-38).
