And it shall come to pass, that every one that is
left of all the nations which came against Jerusalem shall even go up from
year to year to worship the King, the LORD of hosts, and to keep the
feast of tabernacles. And it shall be, that whoso will not come up of
all the families of the earth unto Jerusalem to worship the King, the LORD
of hosts, even upon them shall be no rain. And if the family of Egypt go
not up, and come not, that have no rain; there shall be the plague,
wherewith the LORD will smite the heathen that come not up to keep
the feast of tabernacles. This shall be the punishment of Egypt, and
the punish-ment of all nations that come not up to keep the feast of
tabernacles.
Zechariah 14:16-19
