Exodus 8:29-31

Revised Standard Version

²⁹ Then Moses said, “Behold, I am going out from you and I will pray to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow; only let not Pharaoh deal falsely again by not letting the people go to sacrifice to the Lord.” ³⁰ So Moses went out from Pharaoh and prayed to the Lord. ³¹ And the Lord did as Moses asked, and removed the swarms of flies from Pharaoh, from his servants, and from his people; not one remained.
