Zechariah 14:16-18

16And it shall come to pass, that every one that is left of all the nations that came against Jerusalem shall go up from year to year to worship the King, Jehovah of hosts, and to keep the feast of tabernacles. 17And it shall be, that whoso of all the families of the earth goeth not up unto Jerusalem to worship the King, Jehovah of hosts, upon them there shall be no rain. 18And if the family of Egypt go not up, and come not, neither shall it be upon them; there shall be the plague wherewith Jehovah will smite the nations that go not up to keep the feast of tabernacles.
