Exodus 8:29-31

New Living Translation

²⁹ Moses answered, “As soon as I leave you, I will pray to the Lord, and tomorrow the swarms of flies will disappear from you and your officials and all your people. But I am warning you, Pharaoh, don’t lie to us again and refuse to let the people go to sacrifice to the Lord.”

³⁰ So Moses left Pharaoh’s palace and pleaded with the Lord to remove all the flies. ³¹ And the Lord did as Moses asked and caused the swarms of flies to disappear from Pharaoh, his officials, and his people. Not a single fly remained.
