Exodus 8:16–17

Then the Lord said to Moses, “Say to Aaron, ‘Stretch out your staff and strike the dust of the earth, so that it may become gnats in all the land of Egypt.’ ” And they did so. Aaron stretched out his hand with his staff and struck the dust of the earth, and there were gnats on man and beast. All the dust of the earth became gnats in all the land of Egypt.

Then the Lord said to Moses, “Tell Aaron, ‘Stretch out your staff and strike the dust of the ground,’ and throughout the land of Egypt the dust will become gnats.” They did this, and when Aaron stretched out his hand with the staff and struck the dust of the ground, gnats came on people and animals. All the dust throughout the land of Egypt became gnats.

So the Lord said to Moses, “Tell Aaron, ‘Raise your staff and strike the ground. 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. 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 in the land of Egypt turned into gnats.

And Yahweh said to Moses, “Say to Aaron, ‘Stretch out your staff and strike the dust of the land, and it will become gnats in all the land of Egypt.’ ” And he did so, and Aaron stretched out his hand with his staff, and he struck the dust of the land, and it became gnats on the humans and on the animals; all of the dust of the land became gnats in all the land of Egypt.

And the Lord said unto Moses, Say unto Aaron, Stretch out thy rod, and smite the dust of the land, that it may become lice throughout all the land of Egypt. And they did so; for Aaron stretched out his hand with his rod, and smote the dust of the earth, and it became lice in man, and in beast; all the dust of the land became lice throughout all the land of Egypt.
