Exodus 8:15, 19, 30-32

But when Pharaoh saw that he had some breathing room, he got stubborn again and wouldn’t listen to Moses and Aaron. Just as GOD had said.

The magicians said to Pharaoh, “This is God’s doing.” But Pharaoh was stubborn and wouldn’t listen. Just as GOD had said.

Moses left Pharaoh and prayed to GOD. GOD did what Moses asked. He got rid of the flies from Pharaoh and his servants and his people. There wasn’t a fly left. But Pharaoh became stubborn once again and wouldn’t release the people.
