4 I will make a distinction between the animals of the Israelites and those of the Egyptians, and no animal that belongs to the Israelites will die.
5 I, the Lord, have set tomorrow as the time when I will do this.’ ”
6 The next day the Lord did as he had said, and all the animals of the Egyptians died, but not one of the animals of the Israelites died.
7 The king asked what had happened and was told that none of the animals of the Israelites had died. But he was stubborn and would not let the people go.
8 Then the Lord said to Moses and Aaron, “Take a few handfuls of ashes from a furnace; Moses shall throw them into the air in front of the king.
9 They will spread out like fine dust over all the land of Egypt, and everywhere they will produce boils that become open sores on the people and the animals.”
10 So they got some ashes and stood before the king; Moses threw them into the air, and they produced boils that became open sores on the people and the animals.
