28 Pharaoh said, “I will let you go, that you may sacrifice to the Lord your God in the wilderness, only you shall not go very far away. Pray for me.”
29 Moses said, “Behold, I am going out from you. I will pray to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow; only don’t let Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the Lord.”
30 Moses went out from Pharaoh, and prayed to the Lord.
31 The Lord did according to the word of Moses, and he removed the swarms of flies from Pharaoh, from his servants, and from his people. There remained not one.
32 Pharaoh hardened his heart this time also, and he didn’t let the people go.
