29. And Moses said: "After departing from you, I will pray to the Lord. And the flies will withdraw from Pharaoh, and from his servants, and from his people, tomorrow. Yet do not be willing to deceive any longer, so that you would not release the people to sacrifice to the Lord."
30. And Moses, departing from Pharaoh, prayed to the Lord.
31. And he acted according to his word. And he took away the flies from Pharaoh, and from his servants, and from his people. There was not even one left behind.
32. And the heart of Pharaoh was hardened, so that, even at this turn, he would not release the people.
