Zechariah 14:18
If the people of Egypt do not come to Jerusalem to take part, they will have no annual Nile overflow. A plague will come from the LORD to strike the nations who do not come to observe the Festival of Tents.
Deuteronomy 11:10-11
For the land that you are about to enter to inherit isn't like the land of Egypt that you just left, where you plant a seed and irrigate it with your feet like a vegetable garden.
Zechariah 14:12
"This will be the plague with which the LORD inflicts all of the people who have attacked Jerusalem: he will cause their flesh to rot away, even while they're standing on their feet. He will cause their eyes to rot away in their sockets, and their tongues to rot away in their mouths.
Zechariah 14:15
A similar plague will also strike horses, mules, camels, donkeys, and all of the animals in those camps."
