Zechariah 14:17-18
Context14:17 But if any of the nations anywhere on earth refuse to go up to Jerusalem 1 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.
