A Plague of Gnats!

So the LORD said to Moses, "Tell Aaron to strike the dust with his staff. The dust will turn into swarms of gnats throughout the land of Egypt." so Moses and Aaron did just as the LORD had commanded them. Suddenly, gnats infested the entire land, covering the Egyptians and their animals. All the dust in the land of Egypt turned into gnats. Pharaoh's magicians tried to do the same thing with their secret arts, but this time they failed. And the gnats covered all the people and animals.

This is the finger of God!" the magicians exclaimed to Pharaoh. But Pharaoh's heart remained hard and stubborn. He wouldn't listen to them just as the LORD had predicted.
