'Plague' in the Bible

Now this will be the plague with which the Lord will strike all the peoples who have gone to war against Jerusalem; their flesh will rot while they stand on their feet, and their eyes will rot in their sockets, and their tongue will rot in their mouth.

So also like this plague will be the plague on the horse, the mule, the camel, the donkey and all the cattle that will be in those camps.

If the family of Egypt does not go up or enter, then no rain will fall on them; it will be the plague with which the Lord smites the nations who do not go up to celebrate the Feast of Booths.
