Exodus 8:20 MSG

[20] God said to Moses, “Get up early in the morning and confront Pharaoh as he goes down to the water. Tell him, ‘God’s Message: Release my people so they can worship me. If you don’t release my people, I’ll release swarms of flies on you, your servants, your people, and your homes. The houses of the Egyptians and even the ground under their feet will be thick with flies. But when it happens, I’ll set Goshen where my people live aside as a sanctuary—no flies in Goshen. That will show you that I am God in this land. I’ll make a sharp distinction between your people and mine. This sign will occur tomorrow.’”
