Zechariah 14:16-18

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. 14:17 But if any of the nations anywhere on earth refuse to go up to Jerusalem to worship the King, the Lord who rules over all, they will get no rain. 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.
