Exodus 8:21

‘Then your houses and the houses of all your servants and the houses of all the Egyptians shall be filled, something which neither your fathers nor your grandfathers have seen, from the day that they came upon the earth until this day.’” And he turned and went out from Pharaoh.

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.

He spoke, and there came a swarm of flies And gnats in all their territory.
