'Gnats' in the Bible

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 magicians did so with their secret arts to bring out the gnats, but they were not able, and the gnats were on the humans and on the animals.

He spoke, and there came flies [and] gnats throughout all their territory.

Lift up your eyes to the heavens and look to the earth beneath, for [the] heavens will be torn to pieces like smoke, and the earth will be worn out like garment, and those who inhabit her will die like gnats. But my salvation will be forever, and my righteousness will not be broken to pieces.
