Zechariah 14:9; Zechariah 14:16-19
The LORD will become king over all the land. On that day the LORD will be one, and the LORD's name will be one.
All those left from all the nations who attacked Jerusalem will go up annually to pay homage to the king, the LORD of heavenly forces, and to celebrate the Festival of Booths.
Whoever among the families of the earth doesn't go up to Jerusalem to pay homage to the king, the LORD of heavenly forces, upon them no rain will fall.
And if the family of Egypt doesn't go up and doesn't present itself, then no rain will fall on them. There will be a plague like the one with which the LORD struck the nations that didn't go up to celebrate the Festival of Booths.
This would be the sin of Egypt and the sin of all the nations who don't go up to celebrate the Festival of Booths.
