International feast
Quite appropriately, the Feast of Tabernacles is the only Jewish festival which is for “all people,” both Jews and non-Jews. Its coming eternal celebration will be for all the families of the earth:

“It shall be, everyone who is left of all the nations which came up against Jerusalem shall go up from year to year to worship the King, Jehovah of Hosts, and to keep the Feast of Tabernacles. And it shall be, whoever will not come up from all the families of the earth to Jerusalem to worship the King, Jehovah of Hosts, even on them shall be no rain.” (Zechariah 14:16-19).
