Nadab relates the story when Pharaoh takes his chariot out to Goshen to see what happened there when the animals in Egypt all died. He meets Moses who says, “Are you going to let the Israelite people go? Did you notice that God spared his children’s flocks so none of our animals died?” Pharaoh is furious. He refuses. His Hebrew slaves are burning the carcasses from the last plague and Moses throws ashes into the air causing boils erupt on Pharaoh and in all of Egypt.
