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.
They have all gone astray; they are all alike perverse; there is no one who does good, no, not one.
because if you will not let my people go, I will send swarms of flies on you, your officials, and your people, and into your houses. The houses of the Egyptians shall be filled with swarms of flies, as will the land where they live.
So Moses went out from Pharaoh and prayed to the Lord.
But Pharaoh hardened his heart this time also and would not let the people go.
If favor is shown to the wicked, they do not learn righteousness; they corrupt what is upright on the earth and do not see the majesty of the Lord.
