Zechariah 14:9; Zechariah 14:16-19

9 And the LORD will be king over all the earth: in that day will there be one LORD, and his name one.

16 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.

17 And it shall be, [that] whoever will not come up of [all] the families of the earth to Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.

18 And if the family of Egypt shall not go up, and shall not come, that [have] no [rain]; there shall be the plague, with which the LORD will smite the heathen that come not up to keep the feast of tabernacles.

19 This shall be the punishment of Egypt, and the punishment of all nations that come not up to keep the feast of tabernacles.
