Exodus 8:19-21

Amplified Bible, Classic Edition

¹⁹ Then the magicians said to Pharaoh, This is the finger of God! But Pharaoh’s heart was hardened and strong and he would not listen to them, just as the Lord had said.

²⁰ Then the Lord said to Moses, Rise up early in the morning and stand before Pharaoh as he comes forth to the water; and say to him, Thus says the Lord, Let My people go, that they may serve Me.

²¹ Else, if you will not let My people go, behold, I will send swarms [of bloodsucking gadflies] upon you, your servants, and your people, and into your houses; and the houses of the Egyptians shall be full of swarms [of bloodsucking gadflies], and also the ground on which they stand.
