“And it will come to pass, that from one New Moon to another, and from one Shabbat to another, all flesh will come to bow down before Me,” says Adonai.
If the Egyptians do not go up and celebrate, they will have no rain. Instead, there will be the plague that Adonai will inflict on the nations that do not go up to celebrate Sukkot.
In that day “Holy to Adonai” will be inscribed on the bells of the horses and the pots in House of Adonai will be like the sacred bowls in front of the altar.
