Zechariah 14 (KJV)

6 And it shall come to pass in that day, that the light shall not be clear, nor dark:
7 But it shall be one day which shall be known to the Lord, not day, nor night: but it shall come to pass, that at evening time it shall be light.
8 And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.
9 And the Lord shall be king over all the earth: in that day shall 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 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.
18 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(unbelievers) 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.
