Exodus 8:21

21 Otherwise, if you won't let my people go, I will send swarms of insects on you, your servants and your people, and into your houses. The houses of the Egyptians will be full of swarms of insects, and likewise the ground they stand on.

Exodus 8:21 In-Context

19 Then the magicians said to Pharaoh, "This is the finger of God." But Pharaoh was made hardhearted, so that he didn't listen to them, just as ADONAI had said would happen.
20 ADONAI said to Moshe, "Get up early in the morning, stand before Pharaoh when he goes out to the water and say to him, 'Here is what ADONAI says: "Let my people go, so that they can worship me.
21 Otherwise, if you won't let my people go, I will send swarms of insects on you, your servants and your people, and into your houses. The houses of the Egyptians will be full of swarms of insects, and likewise the ground they stand on.
22 But I will set apart the land of Goshen, where my people live -no swarms of insects will be there - so that you can realize that I am ADONAI, right here in the land.
23 Yes, I will distinguish between my people and your people, and this sign will happen by tomorrow."'"
