“Then all who survive

Of the nations

That have come

Against Jerusalem

Shall go up,

Year after year,

To worship the king,

Yahweh of hosts.

They will keep

The festival of booths.”

This is a universal appeal to all countries to come to worship Yahweh, with a particular remark about those who had fought against Jerusalem.  Yahweh wanted them to come every year to worship him, the king, Yahweh of hosts, for the festival of Booths, Tabernacles, or Tents.  This was usually in the fall, when there was a renewal of the covenant.  There was no mention of any other Israelite religious festivals.
