But if you will not let My people go, I will send swarms of flies upon you and your officials and your people and your houses. The houses of the Egyptians and even the ground where they stand will be full of flies.
On that day the LORD will whistle to the flies at the farthest streams of the Nile and to the bees in the land of Assyri
He spoke, and insects swarmed—gnats throughout their country.
He sent swarms of flies that devoured them, and frogs that devastated them.
