The Lord said to Moses, “Tell Aaron, ‘Raise your staff and strike the ground. The dust will turn in to swarms of gnats through the land of Egypt.'” So Moses and Aaron did just as the Lord commanded them. When Aaron raised his hand and struck the ground with his staff, gnats infested the entire land , covering the Egyptians and their animals. All the dust of Egypt turned to gnats. Pharaoh’s magicians tied to the the dame thing with their secret arts, but this time they failed. And the gnats covered everyone, people and animals alike.
“This is the finger of God,” the magicians exclaimed to Pharaoh. But Pharaoh’s heard remained hard. He would listen to them, just as the Lord had predicted. (vv. 16-19, NLT)
