'Plague' in the Bible

"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.

A similar plague will also strike horses, mules, camels, donkeys, and all of the animals in those camps."

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.
