So Pharaoh said, "I will let you go to sacrifice to the Lord your God in the wilderness, provided you do not go very far away. Pray for me."
29
Then Moses said, "As soon as I leave you, I will pray to the Lord that the swarms of flies may depart tomorrow from Pharaoh, from his officials, and from his people; only do not let Pharaoh again deal falsely 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: he removed the swarms of flies from Pharaoh, from his officials, and from his people; not one remained.
32
But Pharaoh hardened his heart this time also, and would not let the people go.
